"Well i have 16.5 hrs on the 350 I installed in my 1981 18 footer with a volvo 280 leg. I have an edelbrock performer with a rochester 4bbl
I have 2 props.
The first is a 14x19 and runs 30mph at 3000rpm with a WOT of 44mph at 4200rpm.
The second is a 14x23 and runs 34mph at 3000rpm with a WOT speed of 47mph at 3900rpm.
This was done at an elevation of 3000 feet and 80F. I only ran WOT for 30-45 secs max.
I think I should be getting more RPM and speed out of those props with such a little boat.
It seems as the speed increases the bow begins to plow a little. The boat has trim tabs but no trim on the leg.
How do I get more rpm?
Timing?
Trim? - Would mean a different upper on the leg I think.
Here is a pic of the boat and drive. I emailed the manufacturer and the weight including a SBC is about 2400lbs. I am sure I should be getting more out of this.
Thanks.
