Hey Folks,
I've been tweaking and tuning my 89 sunsport and need some help. Currently I'm running a 3 blade Acme prop and getting about 32 WOT at around 4800 RPMS. I'm at about 6K feet in elevation so that's a factor.
I can't help but think I should be able to get more top end out of this boat, or that my RPM's shouldn't be quite so high at this point. I've talked with the folks at Acme and they helped me with the prop so I think that's dialed in right.
I was wondering if there was anybody else out there with a 1989 Sunsport that I could compare some performance info with? I did a compression test last fall and things were good there, but who knows where they're at now. This may just be the characteristics of this boat so thought I'd ask before I continue digging at the motor and prop.
We slalom as opposed to wake-boarding so that's why the interest in slightly higher speeds.
Thanks,
John
