Spare Prop

[mippel]

Hello,
I have a 2004 Regal 1800 with the VP 4.3 with 1.66 SX lower. Currently it has a Volvo 14-3/4" X 21p SS prop. I would like to get a aluminum prop for a spare. I did get it out on the water today so here are my answers:

1) Performance issue you are trying to correct: Have a spare prop
2) Current prop manufacturer, model, aluminum or stainless and as a minimum: Volvo Stainless #3860709
3) Current prop diameter and pitch (required): 14-3/4" X 21p
4) Wide open throttle RPM and speed with an average load (very helpful): 4500 rpms 50mph on GPS with 26 gal gas and 650 lbs of people and stuff
5) Engine/drive make, model, year, and HP: 2004 VP 4.3 190 HP
6) Boat make model, year, length and weight: 2004 Regal 1800 2450lbs from mfg


So should i stick with a 21p aluminum prop for a spare? Or go to a 19P just in case i want to pull someone on skis or a tube?

Re: Spare Prop

With the 19 you would be closer to 5000 rpm, is that acceptable for that motor?

Sorry, suggested RPM is 4200 - 4600.

Re: Spare Prop

Is this verified, cause I was thinking 4400-4800 for the BS'ed 4.3s.

I would look at a hustler of the same pitch you have now, or possibly two hustlers (one hub) in both 21" and 19" Would be about $100 for single pitch or $160-170 for both.

In the VP manual it lists 4200-4600 for the 4.3GL-D.
