I have a 115 Evinrude w/ a 20" shaft mounted on an '86 Bayliner with a 25" hull, this leaves my cv plate about 3" above bottom of the hull. My question is would a fixed jack plate mounted upside down be ok or do I really need to spend the extra $300 to get the shaft extender?<br />This is the jack plate I'd like to get - http://www.thmarine.com/product.cfm?PRID=22

Have you tried to run it yet? A really good prop may take care of the situation.

Munina, You do not need to mount the Jackplate upside down, just mount it 3.5 Inches lower than the transom top. Now install the motor and test and raise, test and raise until it is optimum.<br /><br />You may get away with using a really good prop, or you may not. Your best bet is the Jackplate.

Muninah06,<br />I had the same issue a few years ago on a Merc. You can get an extension for your lower unit, short shaft to long shaft. More than likely a lot less money than a jack plate and it's fixed forever. I assume you can also do this to a Rude?<br />Good luck. Hope this helps.

If you mount it lower via some sort of plate just be careful when tilting. Things tend to hit that way. I'd try it as is. Unless you have a worn out prop -- which would need replacing anyway. Actually if you went to a good 4 blade you might have to be that high anyway. Or even a good Turbo 3 blade.
