After reading many posts here and checking my RPM's with a couple of props, I've come to the conclusion that I should try raising my motor at least one hole. I have a double step up hull (stratos). How difficult it it to remove the top two bolts and loosen the bottom ones and use the front trailer jack to raise the engine, and more importantly what can go wrong? Can I do this by myself? Is there any danger of the engine pulling away from the transome while being held by only the bottom bolts? Would it be better to use a floor jack to raise the motor?
