Cavitation Problems with Moombas

[Djdompe]

Finally about to get my own boat!!! Looks like so far that the Outback V is the one for me, but am hearing that there are cavitation problems coming out of corners. Has anyone ever encountered this? Or for that matter, can explain to me exactly what this means? Any help would be appreciated

Any boat can cavatate coming out of a corner-its just the prop getting some air and slipping. Not a real big deal-my lsv will do it sometimes.

Sounds like something that can happen with any boat, whether a cheaper boat or a mastercraft... correct?

I noticed it a heckuva lot more often with the old outboard boats than with any of the inboards I've been around. In fact, I can't recall ever noticing it in a DD boat.

I think what your hearing is someone who had an issue or thought they did and said exactly the same thing without knowing what they are talking about. If you think about, cavitation is generated by the propellors speed and mass, not by the hull. So in essence any boat is subject to it. Cavitation often occurs from poor propellor design or improper pitch for the application, that is not the case with modern inboards. Cavitation is often thrown out as a catch all when one of two things occur, the person saying so has no clue or the issue (if one exists) cannot be found.

When i test drove my LSV the dealer pulled a move on us and i swear we were going over! Ever seen an LSV in a high speed spin? I didn't think it was possible but it is and let me say i don't want to repeat it!

Anyway the point is even in that extreme turn/spin the prop did not cav or slip. I could see in rough conditions and a improperly trimmed boat the prop slipping. Dunno, i don't do powerturns as they have no purpose.

Your 100% right Kane and mostly because of trim.

Nope i havent.

I have owned 5 boats in the last 25ish years. I worked on a US Army rec. area where we rented out all kinds of boats that I got to play with. With this being said I have been on several outboards that I could get the prop to cavitate and we actually ordered short drives so that they would do it, it acts like a governer when you turn tight. But I have never been in an inboard and heard one do it. And I will and do crank them over at top end! If you get the prop out of the water on an inboard well then maybe you should be kissing you a&& goodbye!

Sweet thanks a lot guys! Hopefully soon I will join the ranks as a Moomba owner
