1981 Mercury V225 on a 20 Master Angler

[Bigshrimpin]

Ben - You're probably right. The motor is 24 years old, but still has 120 - 122 psi in all 6 cylinders. I think the prop that I'm using is a big factor. It's a little dinged. The v225 was re-rated to v200 in 1983 when merc chaged over from rating HP at prop instead of the powerhead.

R. Nahim - What diameter 17 pitch mirage do you run?
I believe those mirage props are progressive pitch props (also heavily cupped).

The best part about the engine is 3mpg @ 3800 rpm => 31/32mph cruise (per Navman)

glad to see some info on what mine will do.
I just got mine ready and will be splashing this weekend.
I also have a 20 cc with a 98 merc 200efi.

Jorge,

Were will you splash you're boat. Are you in South Miami. I'm curious on you're speed. If you are close to my neighborhood I'd like to show you my boat.and share ideas

Hello,

I would like to get together and compare "notes" on our boats.
I was recently on a little R & R in the keys and the boat ran great.

Call me 786-287-5370

Thanks guys for the info on the props.

I'm still running the dinged aluminum 17", but a new prop is on the way. This weekend I fixed the external Trim and Tilt pump (so the motor stays up w/o a pin underway), the boat found some extra speed and hit 46.2 mph with two people and a kicker.

On my way to the Bar to visit Strick (thanks again Strick) . . . I passed by a few Marine Patrol boats underway taking a beating in the wind and current. Man I love this boat . . . especially over 35mph in the chop.

Got the new 14.5" 19 pitch Aluminum prop.
(Not going stainless until I learn my way around the Sacramento Delta)
48.5 mph with the motor trimmed up 5500rpm
Cruise at 3800 is 34 mph - 10 GPH
40 gallons fuel, 2 people + kicker.

45+ mph is scary in this boat . . .

When you're ready, I have a 17 degree stainless prop for that motor. I had it on my 150, but I was not making RPM's at WOT. The prop is probably perfect for that boat. It's either a vengence or mirage. Perfect condition.

Bigshrimpin,

Diameter on the Mirage is 15 1/2. A Lazer 14 x19 s/s prop would be the fastest for a 20 ft SC. I have a 20SC with a B-bracket and trim tabs. I wonder how the ride and performace compares to a transom mounted engine.
