Do you have a working tach on it? Sounds like your turning maybe 5K RPM's which is way to low. I would expect alot closer to 40 or low 40's out of that engine on that boat. I know that 140 would hang would just about any 150 on a simliar boat, and 150's will push a V-20 to 40-42 no problem. Also it looks like your getting alot of spray off the foot, so your engine may be mounted to low. Check to see what prop you have on it as you should be spinning a 15 pitch stainless, anything bigger and it will bog the engine down. And that 1.8L engine HATES being lugged, it likes RPM's. The limiter in it is set at 6100, and I used to prop it so that if I trimmed it just a tad high it would bump the limiter. That always gave me the best fuel milage, and the best power out of it.
