Okay guys I measured the transom and it is 480mm high and measured the cav plate to the centre of the screw clamps 520mm high. My cav plate when level is sitting 35mm under the keel at the present moment.

Now I ask what is the solution to my problem?

2 choices

take it back to the dealer and get the right motor fitted
build up and strenthen your transom

Tinn , your transom is only 10 mm longer than mine, cav plate should be about level with bottom of boat not keel , sounds like you need to come up about 35 mm . Would that then put your cav plate in line with bottom of boat ??If it does work out will you have any screw purchase on transom available??.
The deal you got in my books is not fair, but if you would rather sort it yourself , you might have to see if bolts between outboard and transom
can be moved up and motor put higher up. Another dealer closer if told of the last dealing , may put your faith back in the marine profession .
I think a small amount of money for welding up old bolt holes and new bolts etc..
Will sort the problem ,

Thanks for the photos robersl that was very kind of you.

Saurian: If I come up that high I beleive I won't have any screw purchase on transom left.

What should I do people?

I am very confused in what to do.

Mate I would be taking it back to the dealer who sold it to you as Garry(Spaniard King) suggested, and get him to fix it either by changing leg length or modifying the transom to suit. I would not be modifying the transom as this could lead to insurance/resale/cosmetic pain further down the track. Its not up to you to fix a dealers mistake. When I bought my boat the dealer set the trailer up incorrectly, it was taken back and fixed at no cost to me and now is as it should be. In the end its up to you but I know what I would be doing if it were me.

Cheers and Beers

I spoke to dealer this morning he recomended to me to get a piece welded onto the transom. I am very unhappy with the dealer never to use them again or speak to them again. He told me that the cav plate should be 15mm under the keel which means 25mm under the boat curently it is 45mm under the boat meaning a lift of 20mm is needed. So before I first lifted the engine the cav plate would have been 60mm under the boat and he tells me it should have been 25mm what the f were they thinking when they put the engine on can't understand they know where it should have been mounted. I will be lifting it 25mm by placing a 45mm piece of aluminium on the transom then bolting the engine in place. I will then see where the clamp screws end up take it for a test run then get the aluminium welded. Screw the dealer and other yards do it yourself and you will get the job done.

not happy

Saurian: I forgot to tell you that I already got another well known dealer to lift the engine should have just done it myself. They assured me that the engine should be where it presently is. Every one that has seen the engine at boat ramps freinds ausfishers say it must be lifted so musch for good service from a dealer that we all know. 2 Dealers both didn't fix the problem

Tinn,

the best height for your motor is always worked out by trial and error. Guesses and recommendations only go so far. As you say, try it out first and if it works good, make it more permanent.

BTW, I believe that it should be as high as possible without excess cavitation/ventilation on turns. A small amount is acceptable.

Let us all know how it turns out.
