help/advise please

hello everyone, I have been lurking here and reading for a while now and would be greatfull for a few pointers from those in the know.

I am looking to buy a small inflatible of about 3.4 to 3.8 mtrs long, now the hard bit !. I allready own a very good 15 hp 2 stroke mariner that gets used on another boat, it is a LONGSHAFT model.

can anyone think of a boat in this size range that I could use with this motor ?. thanks in advance.

ps. if its not possible to buy a boat to fit the motor, could the transom be raised up a couple of inches to acomodate a longshaft or is this a bad idea ?.

You can use that HP engine on any sib rated for a 15, much faster conversion is to buy a 5" transom mount to raise engine, modifying height is time demanding as we are not talking about small height transom shims...

Happy Boating

I used a 25hp mariner long shaft for ages on the back of my sib. Adjusting the transom was easy as it had a low area where the outboard mounts, I just folded some stainless over the top to make it level all the way across.
Might have a pic...

Sorry can't help you on this one, check Google for transom's extenders. This one is probably custom made by someone...Probably can make one for yousrself at a metal carpentry ?

Happy Boating

I have the means to cut and weld mild steel, so may give this a go and get it galvanized and then paint it so it blends in.

That 5" transom height extender looks very capable of handling the engine back-torque, if properly mounted. Thanks for posting the image.
