I'm a new owner to a '98 SR24. I'm having speed and RPM issues.
Engine - '04 496 H.O. with 150 hrs.
Prop - 26" Bravo 1 four blade ss. Prop just scanned by Airmarine in Chicago and it is in good shape.
Drive - Brave 1 with 1.50 gear ratio
I do understand I am underpowered and will correct it in the future, but I am only pulling 4100 rpm's at 52/mph on gps.
I had the throttle position sensor checked and at WOT it reads 99.8%, so that isn't the issue. The plugs were recently replaced. I have had no other engine scans done, yet.
The boat gets on plane without an issue and the engine sounds healthy. I see no hull damage.
I am going to try a 24" prop this weekend, but have been told that I should be able to turn the current one at 5,000 rpm.
Most ads for this boat similarly powered claim top speeds of 70-75 mph. I figured with the current set up I'd at least be in the mid 60's. Any ideas?
