2005 Sea Ray 200 Sport 5.0

[Scott06]

I have similar boat - 2004 200 sport with a 5.0. Only differences would be I have a 4 bbl Edlebrock on mine (maybe 240-250 hp vs 220) and my drive ratio is a 1.82. My boat was originally a 4.3 (previous owner cracked block). With the V6 drive ratio I had to step up from a 19" pitch to a 21" pitch to keep WOT at 4900 or so.

Your numbers basically match up with mine and I would agree you should be able to swing a 18-19P 4 blade just fine. Would also think a 21 would work but just be sluggish out of the hole. Depending on which prop I run - I've gotten the following:

4 blade 21" Vensura- 44 Mph, 4900-5000 rpm, 20% Slip, occasionally touch the limiter
3 blade 22" Enertia- 47 mph- 4850 ish rpm I think slip was like 14%
4 blade Revolution 4- 48 mph 4900 rpm - I think slip is 12%, real nice hole shot with medium PVS plugs. Biggest difference on top end the rev4 has enough bite to really trim up and gets ab out 3-4 mph more vs max trim I could run for the Vensura. Engine will get another 300 rpm when really trimmed up and the prop is near the surface.

I would think with the drive ratio differences between our two boats you'd see similar results with pitches 2" lower than I'm running with my jackalope engine/drive. My use is primarily watersports with a full load of people- so with this boat (beamy and heavy) a 4 blade seems to do the trick well.

My drive ratio is 1.62. Motor is all stock, not sure anything has ever been done to it. Starts up everytime and seems to run fine, just thinking its maybe not producing the power it should. We don't do much watersports, but are generally medium-heavy load. Between the kids toys, all the crap my wife totes along, and a FULL big soft sided cooler, plus usually a couple more adults it seems we are fairly heavy.

New plugs, wires, cap/rotor, fuel filter, accelerator pump, water separator. Motor ran better, but didn't gain any RPM as I had hoped. Still need to check timing. Got tach to quit jumping around, and at 4300-4400 rpm, All I could get out of it was about 43-44mph. That was GPS with the 17p Solas HR4.

Haven't run the numbers to know slip yet, but i'm still a little baffled as to why I can't even reach WOT with a 17p prop, unless that specific prop just happens to behave like a higher pitched one with all the cupping?

I have a 4.3 Volvo GXI 225hp and I have no problem spinning a 19" SS solas 4 blade prop. 4600 rpm and 47 mph on gps

Have you verified the accuracy of the tach?
