H!
Just bought a 50s or 60s Kayot pontoon boat. Its sits very low in the water, this is likely do to the steel pontoons and the custom engine pod with omc 2.5l and stern drive someone added some time...
Performance of the boat is only 12 MPH even though it has at least 120HP. When you push the boat to max RPM of 4300 it will go 12MPH, the bow comes up and the front 12 or 18 inches of the pontoons come out of the water completely! The back of the boat sinks down and the stern is I think actually touching or skimming the top of the water. The wake is like a tidal wave, it is HUGE for a pontoon boat, its a very big hump. I went to the bow while my wife was driving and looked under the boat, it looks like this is because the motor pod is v shaped on the front and is in the water. There is a TON of turbulence under the deck of the boat, the back half of the boat is engulfed in water spray, much worse than a normal pontoon boat. Its almost like a giant surfboard with a motor and propeller.
I know this thing is never going to be a fast boat, and that is fine. But I think it has a lot more potential than where it is currently at. I know nothing about hydrodynamics or pontoon performance. Should I add strakes? bow weight? a foil connecting engine pod to steel pontoons? The motor and stern drive I think are a stinger omc? I think the front mount of the engine might be manually adjustable therefore changing the trim of the stern drive? Should I play with this?
I got this for almost nothing and love its cute old school looks, just want to iron out the bugs of something someone may have done with the i/o omc setup... Once I get new tires and bearings on the trailer I can take it out of water and see just how far the motor pod hangs down compared to the pontoons. It seems like it has enough power to come up on plane, but doesn't because of so much weight in the back? It seriously lifts the front up and the stern down...
