1 Calibration Procedures: Setting the Ignition Timing Correction Selecting an Advance Curve Setting Rev Limit RPM These Instructions are for Tempest II Ignitions Only Rev. C // Severe engine damage is possible if the engine timing is not properly set. Engine Timing Overview: The Sea-Doo RAVE engine is built with excessive tolerance in the positioning of its ignition pulser coil. The pulser coil must be precision positioned relative to the flywheel to achieve accurate ignition timing. Otherwise, poor engine performance or engine damage may result. The ignition sensor in the RAVE engine can be as much as to + out of position, a error compared to a ½ error which other engine manufactures routinely achieve. The Rotax RAVE has up to times this error. This information is not intended to be a negative statement regarding the Rotax engine, but to make clear how important the matter of accurate engine timing is to the performance of your engine. An example of the effect a timing error will have on your engine will be helpful for a clearer understanding. Assume that the sensor has a position error of. This means the ignition timing will have more advance over the entire timing curve than it should have. The chart below shows the effects of this kind of error. Operating Mode Correct Timing Actual Timing Result Cranking BTDC BTDC Hard starting, backfiring, engine damage Idle BTDC BTDC Uneven idle, stalling in water. Acceleration BTDC BTDC Piston damage. High speed BTDC BTDC Overheating, detonation, engine damage Proper engine timing is every bit as important as mixing oil with your gas. It must be set precisely to match the requirements of the engine for the type of riding you plan to do. The Tempest II Ignition was designed specifically for the RAVE engine and includes provisions for calibrating the timing of the Rotax RAVE engine. Setting the Timing Correction Switches Virgin Engine: If your engine case has never been split, the timing correction may be performed using the following procedure.. Locate the factory timing correction number stamped on the engine near the flywheel cover. The number is between and.. Locate the corresponding number from the Timing Correction Factor in Figure. Set the switches exactly as shown. Failure to follow this procedure properly may cause damage to your engine. Test Start the Engine (Virgin Engine only). Be sure to have completed steps and above to set the Timing Correction switches for your specific engine.. Depress the Start button and the engine should start. When started, DO NOT rev the engine. If the engine does not start, check the Yel/Wht and Violet wire connections.. Depress the Start button and the engine should stop.. Start the engine and pull the lanyard. The engine should stop. If not, check the Blk/Yel wire connection.. Proceed to Selecting an Advance Curve section on page.

2 Violated Engine: If your engine case has been split, the following procedure must be performed for proper engine operation. Timing the Engine to Determine Timing Correction Value This is the preferred method even for engine has not been repaired or modified. It guarantees the best results and the highest confidence that the timing is being correctly set. Note: If you do not have the required tools or are not confident in performing the procedure as outlined, please consult your local dealer or other qualified person for assistance. Tools Required: mm wrench mm wrench Spark plug wrench Tachometer (if boat not equipped with one) TDC dial gauge Timing light Pointer tool (included with Tempest II) Timing calibration tape (included with Tempest II) Alcohol wipes (included with Tempest II) This is a good time to read again the Engine Timing Overview on page to have a firm understanding of how important the following procedure is to the operation and service life of your engine. Setup for Engine Timing Measurement. Remove the two breather hoses just forward of the gas tank along with the accompanying grommets used to hold them in place in the hull.. Remove the black or gray plastic drive shaft safety cover from the rear of the engine. There is a drive shaft hanger bolted to the bottom of the safety cover. This hanger bracket must be removed first. Locate the two mm bolts, one on each side. Remove these bolts and lift out the hanger.. Next, remove the two mm bolts and flat washers, one on each side of the safety cover. Remove the cover and set it aside.. Remove both spark plugs.. Using the dial gauge, insert it into either spark plug hole and locate Top Dead Center (TDC). DO NOT use the starter motor to turn the engine. Manually turn the power take off (PTO) that was exposed in step. Leave the dial gauge in place.. Using the alcohol wipe, carefully clean the top area of the PTO s outer edge between the and o clock positions.. Next remove the backing paper from the Timing Calibration Tape and fasten it to the area just cleaned. The arrow on the chart must point in the counter clockwise direction when viewed from the rear of the engine toward the front. Or if you prefer, with the arrow printed on the timing tape pointing toward the carburetors. Be sure the black mark for zero degrees (TDC) on the tape is positioned near the top center, o clock position of the PTO.. Insert the nylon jam washer into the ¼ hole in the rear engine mount. This hole is directly above the PTO TDC position.. Insert the short end of the pointer tool bracket into the jam washer. Apply firm pressure to the bracket until it is inserted completely into the washer. The bracket is properly inserted when comes to rest on the head of a cap bolt directly beneath the jam washer.. Slide the pointer along the bracket to align precisely with the black TDC marking on the timing tape.. Repeat step and confirm that the pointer is at TDC on the tape. Readjust the pointer as required.. Set the Timing Correction switches to setting as shown in Figure.. Remove the dial gauge and reinstall the spark plugs and plug wires.. Attach a timing light per its operating instructions. Page

3 Measure the Engine Timing There are two timing marks on the timing tape besides the black TDC mark. One of these marks will be used to set the timing correction for your engine. Determine whether Blue or Red is the color to use for your engine. Black - TDC Blue - Timing mark for / XP engines. Red - Timing mark for all other engines including all models.. Start the engine. Run at idle only. DO NOT rev the engine.. With the help of a second person, hold the engine between RPM. Using the timing light, note the pointer s position relative to the proper color mark (Blue or Red). Is the pointer on the A (Advanced) side or R (Retard) side of the mark? Stop the engine. NOTE: Look through one of the open holes used by the vent tubes removed earlier to get a clear view of the timing tape and pointer. Set the Timing Correction Switches If the pointer is on the Advanced side A. Referring to Figure, add of retard by changing the correction switches from setting (- ) to setting (- ).. Check the timing by repeating the Measure the Engine Timing section.. If the pointer is still toward the advance side, set the switches to setting (- ) then setting (- ) positions. Check for timing alignment after each change. If the pointer is on the Retard side R. Referring to Figure, add of advance by changing the correction switches from setting (- ) to setting ( ).. Check the timing by repeating the Measure the Engine Timing section.. If the pointer is still toward the advance side, set the switches to setting (+ ) then setting (+ ) and finely to the (+ ) position. Check for timing alignment after each change.. Note the timing correction number that matches your final switch settings and write it on this sheet.. Reinstall the watertight cover on the switch. Put the Boat Back Together. Remove the timing pointer from the PTO. The timing tape can be removed or remain in place.. Reinstall the safety shield with the flat washers and mm bolts.. Reattach the hanger bar with the mm bolts. Insert the grommets and breather tubes in their mounting holes just forward of the gas tank.. Proceed to Selecting an Advance Curve section. Selecting an Advance Curve Curve Selection Overview: The Tempest II Ignition has four built-in advance curves. The advance curve you select must be properly suited to the engine configuration and how you ride your boat. Do not assume the curve with the most advanced timing is the best. The best advance curve is the one that gives you the best performance. If you are not sure which curve to select, please consult with you local dealer or other qualified person to determine the optimal curve to use. Whether you have a stock, limited or heavily modified watercraft, the Tempest II Ignition will work flawlessly for you. Each of the four advance curves is designed for a specific type of engine configuration and riding style. Refer to Figure for graph of each curve for a comparative view. Using Figure as a guide, set Switch B, positions and to the desired curve. Page

7 Setting the Rev Limiter Switches Proper setting of the Rev Limiter RPM is important to ensure that the engine is not damaged from over-reving. The following procedure is recommended for determining the ideal limiter setting.. Turn all five rev limiter setting switches to the ON position. See Figure (Switch A, positions through ). This sets the limit to its maximum setting of RPM.. Run your Sea-Doo on smooth water at the highest speed you can attain.. Note the RPM reading on your tachometer.. Return to shore and set the limiter RPM to the tachometer reading rounded up to the next RPM. Example: If you got a reading of RPM on your tachometer, set the switches at the next highest RPM setting. This would be RPM. Rev Limiter All Switches OFF = RPM (lowest possible limit setting) Turn switches ON to increase REV limit. Switch A Example: For limit set at RPM RPM = () OFF ON Figure Switch setting for RPM is () +. Turn ON switch # () and all others OFF. Note: Whenever you make changes to your engine or boat hull (from the air cleaner, exhaust system to ride plate), remember to repeat this test to determine if rev limiter settings must be changed. If you determine that a lower setting is required, this is a strong indication that the changes have cost you power and performance and it might be advisable to rethink what you did. Reinstall the watertight covers on all switches. tech-support@adventproducts.com E. La Palma Ave., Suite F Anaheim, CA - - FAX Page Sea-Doo is a registered trademark of Bombardier
