Thanks chris

Oh yes, I had a 60 clamshell on mine, managed one run off with it as it was poorly. I now have a Yam 55 on it which goes well.
Just make sure your insurance is happy.

LOL - and have your aft sphincter checked for Retention Functionality.

That'll be one sporty rig

I wouldn't fancy going any higher than a 60hp, I did consider a ex-RNLI 70hp but was advised against it. Minimum hp for an SR4 is 50hp anyway....

how do you stop the chining? I used to have an SR4 with a 40 yammie 2 stroke on and started to chine walk at 28kts. Surely with more power your just going to chine walk more and more violently?

no Chewy's wired up differently from you! Whether it was wise to recommend putting a 60HP engine on a SR4 to a guy who's still at school might be a different issue.
