It could be weight, right?Īnyway, Searay recommends a 19P Vengeance for this boat/motor combo and the H5 is to match the same pitch according to Mercruiser albeit at a slightly lower top end. So, I found a 19P on Craigslist that showed up Friday and I ran it for the first time today with a similar heavy load of 6 adults and a child.

It was also easier to maintain speed which I thought was interesting. I was not able to test the top end since the lake was not smooth enough but still achieved 40 very easily.
I'm thrilled although I honestly have nothing else to compare it to except another H5. The school of thought on the High Five is to stick with the same pitch if that pitch is working for you right now. So, if you are a 17P now and you don't overrev, you should stick with a 17 H5. I have personally never tested any other prop except the High Five as that's what came with my boat. We boat at very close to sea level (3-500 feet) and run a 19P High Five now. I also have a 21P that came with the boat. The boat is pretty weight sensitive with the 4.3 and a heavy hull to boot. The 21P is great for two people and will run at around 48mph at 4800 RPM. However, the motor does not have enough torque to turn that prop (21P) with 7 people and get above 4200 RPM at 42mph (speedo.) It also sluggish out of turns, on plane etc. I was finally able to fine smooth water last night and with 5 adults and 2 kids, the 19P will pull 43-44mph at 4600-4800 RPM. While the top speed is a bit under what I would like, the motor is in the powerband at WOT so it's where it's supposed to be. The SeaRay prop guide is on target for my boat. It is spec'd for a 19P Vengeance and we are back to a 19P prop, albeit a High Five.
