Default New Props..

A buddy of mine has a 2800 SCR that is a real pig .. It takes forever to plane and he has to run it pretty much WOT to keep it on plane.

He ordered a new set of props, they are both 4 blade props.

We are heading to Lake Powell for a week, I'll let you guys know if he is happy with any performance gains they provide.

Hi Philbo. I'd also be interested in knowing the size and pitch of the previos props as compared to the size and pitch of the new. Also the type of outdrive(s) and whether we're talking single or twins. Finally, Outdrive gear ratio as well. I know it's a lot, but these need to be factored when discussing differences. Many variables at play here.

Many thanks. I'm looking forward to the update.

Single engine Merc 7.4L with BIII. No clue what current or previous pitch are. I'll ask him while on the lake.

i have the same boat.

here's the deal.

1. keep the fat chicks off the back seat when going on plane. people on the driver's row or right behind it, in the cabin better if more then four.
2. no trim tabs until your on top of the water on plane, anything else and the tabs are just more drag in the water.
3. outdrive down.
4. push the rpm's upto 4k right off the start, it will pop the bow up and get ay movin.

Props can make a huge difference however I think that size boat needs "twin screws". Stainless steel definitely helps....

After playing around last weekend, we realized that actually using our trim tabs is a huge help! With the addition of our new swim platform, we never really used them before and decided to try the tabs out. HUGE difference! We put them all the way down and we pop out of the water no problem.

Buddy really loves the new props .. Much quicker out of the hole and he can run lower RPM at cruise.

Props are 19 and 21 pitch.

It's not my boat and the lake was real crappy (6' white caps and 60mph gust) when he was out on it so there was no way he could do a WOT run.


He purchased them from these guys - http://www.hillmarine.com/ - and said they were very helpful when he called to discuss his needs.
