Re: mounting outboard

3M 5200 sealant. You can get it at most places. Hopefully where your at, too. If not, ask what a dealer uses in your neck of the woods.

Re: mounting outboard

As for the right height, the cavitation plate should be even,+- 1", with the bottom of the hull at the stern.

Re: mounting outboard

in your opinion ,being to high or to low,would this cause my porpoising problem or am i going to have to put trim tabs on? thanks a lot for the help,greatly appreciated! john
