Prop advice

2 posts in this topic

I have a 150 hp Evirude powering a 17' bassboat. The prop I have on there is a 14 1/2" X 24" stainless steel. Now the problem is top rpm's are 4500, but the top end speed is only 46 mph. My question is how do I get my speed up? Usually your rpm's are higher with higher speeds right? Now if I went to a higher pitched prop wouldn't that lower the rpm's even more and in turn keep the boat at a lower speed? Or is the pitch already too high? Could there possibly be some throttle adjustments that need to be done? My hole shot is great, 0-25 in about 5 sec. and it stays on plain down to about 25 mph. Any advice about what to do for better performance would be greatly appriciated.

jimmy to get more rpm, to need to go with less pitch. are you running a 3 or 4 blade? i would think if yours is a 3 you should be able to turn more rpms, but each boat and motor can be different. i run 13 3/4 dia four blades on my 364 ranger with a johnson 175. my main prop is a 25 pitch. i can trim this to the hilt and run just up to the max rpms for my motor. my back up is the same but a 23 pitch. with this one i have to be careful of my rpms, but does give me a better hole shot when carrying more weight, and i use it in rough water to get on plane faster. talk to some of your buddies to see if they would have other props for you to try. del
