Motor runs great, want to make it greater. 1990 looper 120 (Hey Dhadley)

[alden135]

Hey Guys<br /><br />Now that things are FANTASTIC with my looper I want to see what else I should do.<br /><br />I don't have GPS to verify speed and the speedo is usually clogged so speed is unknown.<br /><br />I can say that I'm getting 6200+ rpm on the tach at WOT. <br /><br />I'm running a 13 3/4x15 aluminum prop at the moment. I also have a 14x19 new alum prop I could put on. Is this the way to go? Will I go faster or get a better hole shot? Should I leave it alone?<br /><br />The thing is that at WOT it still sounds like it wants to do more. I have to cut it back to get below 6k. <br /><br />Should I be in the prop forum? Also, I know a lot of you don't like hydrofoils, but it has helped get my stern heavy boat up a lot faster. <br /><br />J120TLESB<br /><br />Thanks

Good job dude!! <br /><br />It'd almost be a must that we get an accurate speed so we know where we are. But we can still do some testing. Yes, going to a 19 is the next step. Doing so we will lose some r's but then we'll work with the set up to gain the r's back and therefore gain speed & efficiency.<br /><br />What's up with the aluminum stuff?

Well, I bought them from the dealer. I liked the idea of ruining the prop rather than the gearcase if I hit something. It's been my understanding that the SS props perform better, but are harder on the gearcase. Is this wrong thinking?<br /><br />My cousin just got a GPS and I'll see if I can borrow it this weekend.

Stainless props aren't any harder on the gearcase than any other prop. The rubber hub protects the gearcase just like on an aluminum prop.<br /><br />Great plan with the GPS.

OK I'll change to the 19p prop I have and get some #'s Memorial Weekend. I'll post back to this thread next week.<br /><br />Thanks

Dhadley<br /><br />Ok, I switched to the 19p prop and got my WOT rpm down to 5800. I was not able to connect with cousin to use the gps for a speed check though. <br /><br />I'm thinking about venting the prop to improve my holeshot as it seems to take a while to turn up the rpms. Is this a good idea?<br /><br />Thanks,<br />Alden

Can't hurt to try it! It should help.
