Recently noticed fluid leaking from the top of the port side power trim rod on my '05 Optimax 150, Engine trims fine, but, I noticed the fluid level was very low, so, I am guessing I need new seals ?? If so, please, newbie to fixing my own engine here guys, so, I need advice....Is this definitely just a bad o-ring......is so.do i need to buy a spanner wrench, and the entire package of optimax seals ? Thanks guys! Any advice before I spend 150 bucks on a spanner wrench, optimax seal kit and rod removal tool??
