wellcraft v20 with 90 2-stroke

[bgreene]

That's cruising along ok for only 90 hp....... maybe drop down to a 70hp and see if that's better..........or maybe even a 55hp.

60 hp will NOT get it up on plane... at least it wouldn't in the first V I owned..

All those number seem low, my '78 V20 cuddy with a '87 150 Suzuki will run
44 mph and cruises at 28 mph at 3500rpm.. Does that sound right?

If those are your numbers they're great...you must be propped high...I've had two different 150s (1 2 stroke and 1 4 stroke) and I haven't seen 44 or 28 mph @ 3500...

Wish someone with a connection to Mercury could get their hands on the old "Boathouse Bulletins" from Lake X where they tested boat & motor combinations. The 1983 Mercury info for the Wellcraft V20 said 46 mph with their 150 V6 and a 19P prop, 20 gallons fuel, no gear and 2 persons onboard. I tried a 19P prop and went to 17P because real world is 72 gallons of fuel, ice chests and tackle. Mine did about 42 mph real world with a good load and 150 hp.

That's good speed - I'm getting just about 40.0 mph with 150 Johnson and 1/2 tank - 30 gallons on my V21. That was on the ocean, not flat so might get a bit more. With 150hp generally 38-42 mph seems the WOT speed.

Hey jasoncooperpcola why are you so Anti-Suzuki? just wondering..

[bcmarinamanager]

My 1992 200 Merc gets mine with curtains, 1 person, half tank (30G.) on a clam day, 2 way average via Garmin at 42 WOT and trimmed.

I have a Johnson 150 ocean runner with a 17p prop with 5 people & gear and flat lake I top out right around 40 - 42 mph. Not sure what it would be just 2 people and light gear.

My V 21 goes about 140 mph WOT.........downhill......

Sorry, can't resist.
