Those low power Volvos need VOLVO props.Michigan make a great wheel but Volvos run best with a Volvo prop.It probably will perform better with OEM.
I was asked to look at a friends boat:said it wouldn't get out of its own way.I did all the usual and coudn't find anything.A real head scratcher.
As I was leaving I looked at the drive and saw a brand new wheel. I asked when it was changed.That morning.I asked where was the old wheel and they brought out a Volvo prop.I looked at the new and it was a Michigan.I said there was the problem/ The owner said I was full of poop and didn't know what I was talking about. I bet him $100 that was the problem.He said I don't want your money.I'm gonna buy a lot of beer with his.I bought 7-8 cases of Bud with my winnings.His boat ran great with the Volvo prop.J
 
solas makes an excellant prop for volvo for about $97.00 delivered, i got one just a couple weeks ago off iboats and am very impressed with it, i gained an extra 1100 rpm with the different prop, very smooth and planes with almost no effort on a 19ft 2300 lb. cuddy about 30mph wot.i would gaurentee that a 19 pitch is to much for your boat, i also had a 19 pitch prop and went to a 15x15, i was only getting about 4000 rpm wot http://boatpropellers.iboats.com/
 
An extra 1100 RPM is quite a bit of a gain. Your original prop must had either a bent blade or be overpropped by about 4-5 inches, or it had larger diameter than your current prop.
 
it was chopped up pretty bad, theres to many oyster beds here in fl where i'm at, so a prop does'nt last to long. it was a michigan prop and the only markings on it were pr242.someone on here told me it was a 15x19? i was suprised with such a power gain myself, i expected to get somewhere around 4600-4800 rpm wot, but its at 5100 wot now and with the manual calling for wot at 5500 rpm i'm assuming i'm ok and have'nt gone to small on it? i pull inflatables and kneeboards etc. with the boat so i need the quick plane.
 
Well, I always said that the best prop is the one that works the way you expect it to work (or better). Is your new one also a 15x19 or did you go down to 14x19?
 
i went to a 15x15, i'm glad it worked out good because we don't have the ability of trying any different ones where i'm at the closest prop shop is about a 2 hour drive. the prop actually threw me off when i got it, i thought they sent me the wrong one cause its set up like a thru exhaust system, but there is a plate in it sealing off the back side, i'm assuming so they can use this prop for either application with or without the use of the back plate?

Eastcoast,What motor is in your boat? The 120 in this boat needs all the help it can get.
Look on line and find a Volvo prop.You will find it work better,J
