i have a 95 prostar 190 with the lt1. how do i tell if i have a 1to1 or 1.5to1 transmission. i would like to change the prop this winter and need to know this. i have more than enough power out of the hole and would like to pick up a couple of mph. i have the stock prop now.

Go directly to the man that knows, Eric Johnson @ http://www.ojprops.com/contact_us or contact him by pm, EJ OJPROP, http://www.mastercraft.com/teamtalk/member.php?u=1537
Be prepared to give him any info he may need like, current prop info off the hub, baseline numbers of the speeds and RPM's for the current prop, boat model and year, engine size, transmission ratio, function (skiing, barefooting, surfing, boarding, tubing, etc.), ballast use, fuel load, gear, nominal # of passengers, etc. He will need it to determine the best prop for your application.

Your stock prop is a 3 blade 14 x 18 probably turning 5300 RPMs. Turns up pretty quick I imagine.

I have the same set up on my boat 98 PS 190 w/ a Corvette LT-1 slot
I tried a 14 x 20 CUTTER stainless on mine Turning right at 5000 RPMS WOT
and approx 51 MPH

sounds correct. i am still trying to find the markings on my prop. maybe i need to remove the prop nut? turns up extremely quick. i could sacrifice some low end power for some top end.

found it. my prop reads 515 13x12 vl 1 1/8 and is a 3 blade. i thought it was a factory prop. ?????

If you do have a 1.5:1 trans the 13 X 12 is not even close. I would suggest our 14 X 18 or 14 X 20 LC 1 1/8" 4-blade.

You need to double then triple check

w/ a 13 x 12 I don't think you have a powerslot transmission. You need to check the transmission itself before you bid on that prop

Jim_ I checked again after i posted this earlier. i do have the 1.5 trans. i double checked when i did a fluid change on the trans. This would explain why my boat will pull the rope out of your hands if the driver isnt very gentle and hits the rev limiter about 34 mph or less. sounds about right. i had a 89 190 and it had more top end speed. i have owned this boat about 6 months.

That EBay prop looks about right, but I'm not an expert.

However, "Remanufactured" to me means "I hit something hard, and the prop required major rework." Seth Smith to me means "I was too cheap to send it to the manufacturer for repair, so I had a local guy do it." I don't know Seth Smith's reputation, it could be the best prop repair shop in the world, but it's still a repaired prop. It's unlikely to run as smoothly as a new prop.

A new prop is up to twice the price of this one, so I can understand the appeal. Maybe buy this one and if it isn't quite what you want, hold onto it as a spare and buy the right one. Or, just watch Ebay - it's a long time before boating season starts up again, and a lot of props get listed on Ebay. Or, just listen to Eric and buy the right prop first.

i know this is an old thread but i have a question. i bought a 14x20 1 1/8 left hand rotation prop on ebay. please tell me my prop is a keyed prop and not splinned. my boat is in storage and i am pretty sure it has a keyed prop. let me know.

It's keyed and tapered. Splined are newer boats.
So you had a 13x12 on a 'slot?
No wonder it it topped out at 34mph!
14x18 is std for your boat, so the 14x20 should put you into the mid/high 40's for top speed.
