Damaged Cavitation Plate...

[Peter4]

I hit an underwater stump at Monduran on Thursday. It bent my prop and took a 3cm X 8cm chunk out of the anti-ventilation plate on my Honda 40HP four stroke.

Prop has been replaced but I now need someone to repair the plate. I have been told that it needs to be bent, welded and ground back to its original shape.

Anyone know someone (preferably in the Redlands or southside) that can do this type of work?

Your help would be appreciated...

Cheers

Pete

PS I got one small barra!

Just wondering if there is a wrecked motor around you could get the lower leg casing off??
The corrosion factor on the cav plate after welding will be pretty high due to dis-similar metals and the weld metal will be different again. Certainly repairable but it could be not the best two years down the track.
I would be keeping my eyes open for a not working donk up for repair or wrecking.

epifill, sand then paint. job done in fact if you do a good job you may not be able to tell and epifill is as hard as nails

Were you insured? If you were I would be going down that path and having the whole box stripped , checked it is all perfect and a new case.

Depends where on the cav plate and how close to seals as you need the heat not to distort the case so to welded properly it may need to be pulled apart.

I'd be having a very close look for other cracks around housing bolts and cracks around tilt trim when it is that bigger hit.

Talk to Spaniard King on here and get a opinion on if teh case is repairable and true cost if was done and approved under insurance for a replacement lower unit.

Cavitation plate ?? How could that happen Peter4? Come on people lets get it right, no outboard ever made has a cavitation plate, anti-ventilation plate yes but lets not confuse cavitation with ventilation, totally, totally different things.

Perhaps you should alert all those manufacturers of foils also.

Mate some people simply will never get it right Manufacturers you would expect should know better

So the whole world calls it a cavitation plate, but they are all wrong?

[NAGG]

same same ......call it what you want - the bloke needs a welder or advice !!!!

PS - Daz had his done recently .... but it would have been in the Sunny Coast area

Google results. 1,280;00 for ventilation plate and 104;000 for cavitation plate.
Ventilation wins.

I have two different outboards and both manuals call it an anti-cavitation plate. Bugger.

We can argue semantics later...this is not helpful at all.

Back to my original question - who knows someone in the Redlands or southside that can repair it?

By the way, the hit was quite minor and I was surprised at the amount of damage. I was travelling at around 6 knots and just accelearating to get on the plane.

I will post a pic later...

Is it the Anti cav plate or is it the skeg under? I may know someone who can fix it for you, he is at Belmont.
A pic would be good

One thought is ( depending on the damage ) grind it till it's even on both sides and fit a permatrim , but definitely post a pic, Cheers

Arguing the semantics could be helpful if it's the skeg I guess.
