Already have a 177 and manifold both sets of pulleys etc on the shelf. It's easy to get caught up n the bigger blower make more power deal.! But there are 2 things holding me back...

1. I don't want to start eating drives

2. I have a 22 foot boat and a heavy hand, I don't want to get dead......

Fixed it.

Hopefully drives aren't a big deal on the light weight single. The dead part though, that makes since. Are you going to have to modify your hatch? My main reason for not sticking with a 525SC build.

Understand having the 177. Just thought the 250 is so much more efficient , less heat more power.

Work with what you got .

Drive it like you stole it

yep, gonna have to modify or build new hatch. from rough measurement I need about 4 inches more room.

Rob, not to sidetrack your thread, but are you planning on upgrading the drive somewhat?
I was / am in the same boat as you are.
Steel tower, hard shim, blueprinted and so on?

Most likely, after the first time I blow it up..if its fixable,,,,

Your drive will be fine. What I don't get is #2 I don't want to get dead?

You've seen me run a boat with 300 hp...now double that.....

Is alunimum like awuminum ?
