Cavity Plate

[neil.mccrirrick]

Following on from my port list problem, I've just taken the hydrofoils off and found this.

Question.

Do you think this will cause a problem, left like this, and if so best way to fix it?

I could take the engine back as I''ve just bought it, but its a long haul as it was from Oban. Or could I cut the hydrofoils down, or just leave them on?

Thanks

How the hell did anyone do that ! ? Its not even like the break runs to/ from the holes !

I'd guess the foils were added to hide it & may not really be needed . Not sure what affect it would have - but I'd not cut down the foils myself. I guess if you test run it to see you'd find out , but guess some prop/ engine guru will be along to help shorlty .

Take it back to the lying git that tried to cover it up with the foils. There is no way this is coincidence. The foils were there to cover this up.

I think with the prop state and the damage to the anti cavitaion plate that it is fairly certain this has hit something pretty hard at some point, maybe more than once!
I would be slightly worried about the state of the rest of the leg, is it oiltight and are all the bolts and holes holding it together looking OK?

any reason for hydrofoils on an outboard? cant say i've seen any before!
the damage to your plate there looks bad, it will probably cause air to get to the prop when your on the plane, slow you down and make you use more fuel. then again i could be wrong!

Oh dear, oh dear!
My guess, as others have said, the foils were definately added to improve performance as a big chunck of an Important part of the leg is missing.

Best of luck trying to recover your money.
I think, happy to be proved wrong, if you had a chance to inspect the motor prior to parting with cash then you may have a hard fight on your hands.
Very best of luck!

Used to be very popular on Fletchers and the like.
Usefull / Used for underpowered ski boats.

(Unless you mean hydrofoils, bow and stern mounted variety.)

is that your 70hp? I've seen one just like that before. Caused, we found, by a guy trying to split a stuck bottom unit from the leg and hammering at the plate - silly b*****

Oh what a bunt! At a guess I'd agree with Dave. Be a bit hard to do that damage with out the rest of the plate getting wellied by the outboard hitting something wouldn't it? Looks like someones been giving it a fair old whack.

I don't mind taking it back with you Neil if you have too.

It could be grounding damage as well, if it had been on the other side of the plate it could very well have been rocks and kelp picked up by the prop.
I hadn't thought of anybody taking a hammer directly to the plate but then again I find it hard to believe anybody is THAT stoopid!
Who did you buy it from?
