Caravelle 230 owners-Question?

What hole postition do you have your engine mounted? There's a fellow 230 owner out here who hasn't been able to register yet who has an issue with porpoising and needs advice. Any input would be helpful. Thanks!

I have to do some heavy trim with both the engine & tabs to avoid the porpoising issue.. Now that I know the sweet spot - it really isn't an issue for me anymore.

Thanks for posting this topic for me Shel.

I have an '06 Caravelle 230 CC SeaHawk with a Yamaha 225 4-stroke. The motor is mounted on the 2nd hole from the top. Even with the engine trimmed down all the way, it almost always porpoises unless I use the trim tabs at 25% to 50%. When I am offshore in 2' seas I need to have my trim tabs around 75% to 90% of the way down. This is KILING my fuel economy. I am going to try to move my engine either up or down, but I don't know which way to go to fix the problem. Any feedback would be appreciated.

Can you move some weight to the front of the boat?

M_Snow: Even with my wife and 2 daughters sitting up front and nothing but me @ 185lbs driving, I still need to use the tabs in order to not porpoise. Something is definitely wrong in the design or the way the engine was mounted. I've been dealing with it for years, but I probably spent hundreds if not thousands of extra money on fuel by having to use my tabs so much. I am going to try to lower the engine one hole first I think and see what happens.

Might try something like one of these Lift Mounts/Extenders.

I think that I'm going to try to move the engine down to the top hole. If that doesn't work then I may buy and install a Permatrim.

I don't have a trailer and I keep the boat on a lift behind the house, so I haven't done anything yet. I am going to try to move the engine down when I do my next 100 hr service. I'm about 25 hrs away. Until then, I'm just using those trim tabs and wasting fuel. I will post when I get it done.
