How much power is enough on a bullet?

Post by Seth Lehman »

I've started building a bullet boat and am needing to buy a motor. I have been looking at newer 30hp 4 stroke but am not sure if it will be enough power. I would like to be able to to comfortably cruise around 30mph. Anyone have any advice?

Seth,

I have no experience with the bullet, but Glen L has a chart that does a pretty good job of predicting speed based on power/weight ratio.

Based on 800lbs gross weight and a 30 hp motor you will probably hit your 30mph target. Best of luck with your build.

A new 30 would be plenty of power Seth. Even a 25hp I think would be a good match, not a screamer but a very good fit for the boat.

I built an 11 foot TNT which is a similar size boat. I think it weighs a little less than a Bullet depending on which length you build. I have a two cycle 25 HP motor. It has plenty of power and the top speed is just over 30 mph. A comfortable cruising speed is 15-20 mph. Remember, you are basically sitting right on the water in these boats but they are fun :)
