1) Performance issue you are trying to correct.
WOT running about 5K RPM at 44 MPH, I believe it should be max 4800 RPM.
2) Current prop manufacturer, model, aluminum or stainless as a minimum.
Unknown manufacturer/model, aluminum prop.
3) Current prop diameter and pitch (required).
14.5 x 19
4) Wide open throttle RPM and speed with an average load (very helpful)
Running with two people, got to 5,000 RPM at 44 MPH.
5) Engine/drive make, model, year, and HP
1994 Mercruiser 4.3L, I'm not 100% on HP, 210? Maybe?
6) Boat make model, year, length and weight
1993 Maxum 1800SR, 18ft. Unknown on weight.
Really just trying to figure out if I need to change props due to RPM running too high. I don't run at WOT much, just do it for a speed test and saw that the RPM was high. I do have a stainless prop, 14.5 x 19 that I was thinking about putting on there. From my little research, stainless will reduce RPM by 100-200?
Thanks!
