Refer to Se. 4A for informtion on Removl, Instlltion, or Adjustment of Trim-In Limit Bloks. It hs een rought to our ttention tht some ots (predominntly deep-vee hevy ots) will roll up on their side under ertin, speifi, operting onditions. The roll n e either to port or strord nd my e experiened while moving stright hed, or while mking turn. The roll ours most frequently t or ner mximum speed, with the drive unit trimmed t or ner full IN. While the ot will not roll ompletely over, the roll my e suffiient to unset the opertor or pssengers, nd therey rete n unsfe sitution. The roll is used y stern lift. Stern lift n e reted y exessive drive unit trim In. Under these extreme stern lift / ow down onditions instility n e reted whih my use the ot to roll. Weight distriution to the stern n redue stern lift nd, in some irumstnes, eliminte the ondition. Weight distriution in the ow, port or strord, my worsen the ondition. The Trim IN limit devies redue stern lift y preventing the drive unit from rehing the lst few degrees of full trim under. While this devie should redue the rolling tendeny, they my not eliminte the tendeny entirely. The need for these trim IN limit loks or pin, nd the effetiveness of them, n only e determined through ot testing nd is ultimtely the responsiility of the ot mnufturer. WARNING It is reommended tht only qulified personnel remove or djust the Trim IN Limit Bloks or djust the Trim-In Limit Pin.
