Cougar 21 setup - Transom

Hello everyone...

I have a Cougar 21, 22 transom and we have a Mercury 225 Optiamx XL (25" shaft) that needs a home.

The boat will be used for complete recreational purposes and water-skiing. I understand my options are as follows:

1) Change shaft length - Advised best option

2) Mount on the lowest hole + jack plate to have between a c3-4 inch raise - Will increase stress on transom and increasing the height of the engine block.

3) Build up the existing transom Expensive and still wont overcome the lifting the height of the engine block.

I know 'Lars' had a P21 with a with 225 XL wondered if he encountered any problems. I appreciate the best option would be to change the shaft, but bearing in mind this is for a recreational use does anyone have any thoughts of running the Cougar with a jack plate should I be concerned about the transom??

If changing the shaft length is the only realistic option, does anyone have a 20" shaft for sale?? I assume I need a mid-section and bottom box.

Thanks in advance.

Hi Rick - thanks for your reply, assume you're running an XL (25") on your rebuilt transom ?

Did you test the a jack plate setup before going the rebuild route ?

Hi Rick
I have just put a cougar 21 with a evinrude 225hp together for my dad and was wondering what sort of speeds you getting?

Thanks Rick.

Before I go the transom rebuild option which I really would like to avoid. Does anyone have an opinion on the lifter/jackplate option?

I was thinking of a manual lifter with a 2" set back

I would bother going down either route. An XL 25" really isn't the way to go. The COG will be higher than you would want it to be. We had a 25" on a Ring 21 and it was a nightmare...
