I have a 1993 StingRay ( 16.5' ) with a V4 90hp crossflow on it. I am running a aluminum prop that is 13.25d x 17p. We just picked the new to us boat up in August of last year. So we didnt have much time with it before pulling it out of the lake for winter. After finally getting the boat in the water this weekend. I decided to do a few wot pulls and test the boat out with just myself in it. At 6000rpm i am seeing 42mph. But that seems to be a peak speed every once in awhile. But I will always see 41mph at 5900rpm. These speeds are GPS confirmed at both 41 and 42mph on my Garmin. This boat is deffinitly faster then our old 3cyl 60 hp rude that would only see 32-34mph TOPS.. None the less. I am wondering if the 41-42mph I am seeing are good wot speeds for a 90hp on a 16ft boat and also WOULD i pick up any EXTRA top speed AND bottom end pull for tubing with a SS prop ?? I would love to see 43-44 mph with a little extra pull. Im getting greedy !! lol... Any suggestions on SS props and what if any extra speed I would see ? Or is my 41+ mph as good as it gets for a 1991 90hp ? Thank you !
