follow up to fish and ski rooster tail problem

Re: follow up to fish and ski rooster tail problem

Everything I've seen says the standard position is to have the cavitation plate about even with the lowest point of the hull.

As for holding the engine up off the transom -- something like you described or even a nice chunk of hard rubber would do the trick.

Believe or not, my 90 horse Yammy 4-stroke has absolutely nothing in that gap. Scout must be pretty confident of their transom cuz it gives me the willies just lookin at it.

WOW, looks to me like that would really put a lot of stress on the mounting bolts,but, as you said, they must be confident of the strong transom to set it up like that. Iv thought of what I might shim it up with. I'd sure prefer to distribute the weight a little better and take some of the weight off of the mounting bolts.

I've actually seen a lot of outboards with that gap in it. I guess you have to do what you need to get the motor adjusted right. You would think by now that boat manufacturers can get the transom the right length.

I dont think it will be very difficult to adjust the motor up a little bit. No problem at all using the tounge jack as described in a later post. But it sure makes me wonder if this is the original motor that came on the boat. It ran great. It took a little longer to plane out than I am used to, but then again, My VIP had a 90 Chrysler on it with a stingray. I will try to get video or at least pics of the next time I run it. But after all I have read, Im confident that raising it up will fix the issue. But I miss my power tilt my VIP had.
Thanx again

It is perfectly normal to mount a motor above the transom as long as you're using the correct hardware to mount it.

To raise the motor. lower the jack, lock the engine in "down" position. block the engine skag, with lumber. remove bolts and just raise the nose untill it matches bolt patern. support engine "left and right"
hope this helps.

To be clear, loosen the bottom bolts that are in the slots. Remove the top bolts. Don't remove all the bolts.

Done it twice on my boat and it's a piece of cake.

And the weight of the motor should be on the bolts. Don't rely on the "lip" having any real holding strength. Raising it off the transom will not weaken anything.
