The boat(s) I've been looking at are rated in the 150 HP range and I would like to stay within parameters of the manufacturers recommendations. Perhaps going on a 19'1 Polar @ 2000 lbs. The boat will be mainly used for fishing and then pulling kids around on a tube when the fish aren't biting. I like the economy, and engine longevity which four stroke manufacturers are boasting and therefore am giving this power option serious consideration. However, I am not seeing many manufacturers offering 4 stroke power options in this HP range. Can we expect four stroke technology to fill this gap in the forseeable near future or is the inherent market only on the high and low end HP ranges as currently available? <br /><br />Helpful advice appreciated.<br />Kevin
