I have a 2007 m 3 g r

I bought a short shaft 15 inch 50hp tohatsu

Is it the correct motor ? I am.getting a banana shape in the boat when try to plane

What pressure should i fill it to ? What trim angle shoulf i have ??

Cant find specs on my exact model but some outboard shop sized it up and yold me it was a short shaft model

I believe that takes a long shaft. Can you provide the serie and serial numbers off of the transom?

I would of thought it would be the same as my 550 pro long shaft.

The cavitation plate should be approximately 25mm / 1 inch below the the middle low point of the transom.

The correct pressure for the boat when operating is 240 millibar / 3.48 psi. Be sure to check the pressure after the boat has been in the water for a few minutes, as the cooler water will alter drop the tube pressure.

Your "crumpling" problem is caused by a lack of tube pressure or an improperly installed floor.

Just a heads up, it is VERY tough to inflate the boat properly with a footpump. I would recommend purchasing a small 12v electric pump.

the boat is a 2007 mk g r 3.

where can I find spoecs for it?

not the specs for the latest model

a 15 inch transom should have a 15 inch motor?

You can just upload them direct to here... Are you using the app or the Web version of forum?

Your boat is a (roughly) 1980 MkIIIGR and in those days, they took short shaft engines.
