motor height

[back_water]

Ok I have a 1971 glastron V156 sportster. (Tri Hull)

The boat was designed for a long shaft motor, but during rebuild I could only afford a short shaft motor. Prop was inline with drainage plug in transom. I have now cut transom down 3 inches and now prop sits below the hull and cap. plate is inline with the hull.

Now will this help me get more out of my motor. It is a 1980 25 HP Mariner. The boat and motor weight about 1500#. It would run 10 mph with out set up. Should this help me with a little more speed and also help keep motor from captivating on turns.

Thanks,
Nick

Just need to try. set up is a long process. So many variables...

thanks, I am hoping to try it out Sunday and I can give an update once I get back.

The prop plays a very big role in height. Some props are designed to run high and other run low then how the water runs off boat and how high the stern runs. Update with what it does.

I will be heading out at 8am this morning. I have family in from out of town and my father has not been on a boat is 18 yrs. So He wanted me to take him out. I will update on how the boat runs as well as handling tonight.

wow what a difference it made. I gained close to double the speed and power. A lot better in turns and used a lot less fuel on running the same distance. It was worth it to cut the transom down.

Great to hear it worked out for you!
