My dealer sold me a Premier 20 Solaras with lifting strakes and performance sheeting. They told me to go with the HO given it has the larger displacement. The problem I am running into I cant get the RPMs to the sweet spot. I only get 5200 RPMs. The engine drinks fuel. I asked them why not the 90 hp pontoon series and they replied it was a 3 cyclinder and the HO has more power. I have found out even with all that extra power its not working very well on pontoon hulls. I am debating on swapping the engine for a pontoon series engine, I do not know the cost and will find out tomorrow. I have tried different props, 13.5 x 13 Rogue, that prop only peformed at 5000 rpms. I tried a SSP 13 7/8 x 13 and it too only got to 5000 RPMs. A very strange thing happened when running the two stainless props for full throttle for 2 min the engine started to drop in speed and RPMS. I have a feeling this engine is not designed for this boat.
Has anyone else tried an HO 90 on a 2 tube 20 foot pontoon. The HO is 80 pounds heavier than the Pontoon Series engine. I have a feeling that, 80 pounds on the transom and the fuel tank mounted on the left side is making the engine feel more like a four stroke and not being able to spin the prop at those loads.
I need help.
Thanks for reading.
The 11" SSP #763959 may be the one you need for a pontoon boat.
Where can you buy that prop number? I am only getting 5600-5700 RPM on my three blade SSP With light load full fuel. I seem to burn a lot of gas and oil on my 150 HP ETEC Pontoon series.
Your Evinrude dealer can help you with obtaining the correct propeller. What type and size prop do you have on it now? On a pontoon boat it is better to prop them close to the redline rpm at full throttle with a light load on board to allow for the heavy loads during the hot muggy summer afternoons when a crowd is boating with you.
