ok i got my boat back on the water today {very excited}. and the new motor has over 300hp. so when i hammer it it will over rev. it will run to 5k rpm at 3/4 throtle im running a 13x13.it didnt do this before. so i guess im gonna do a prop swap, any recomendations? whats bill running? i was thinking about a 4 blade but the article keith wrote makes me wonder. but i think it will still over rev.but other than that it ran like a top. cant wait to ride this weekend!!!!!!!!!!!!!!!

an inch of pitch will chew up about 200 rpm- that thing is going to fly when properly proped.

how do you adjust the tach to the motor? its still a 351 v8 wired exactly the same as it was before the swap. is there a chance that the tach is going out. is there an easy to test this?
a local race shop built it and i want to limit it with the prop to 5k. do they make a 13x 14? is the first number diameter? |

Call Eric Johnson at 800 359 9730 he will help you. The price is right and he stands behind his product. Why not buy from the factory.
Oh! and he knows speed very well, he raced for years and they have buiding props for over 75 years. |

I'm thinking 13X10 That would allow you to pull up everyone on the lake at one time and keep you under 60MPH at 5K. I do agree with SS 201 Eric has rebuilt several of my props and they are excellent
