Top Speeds For Kaama Surface Drives

BOATMAN302 · 02-02-2006, 12:55 PM

Looking For Speed Numbers As Well As Prop Size And Gear Ratios On Anything Running With Kaama Surface Drives. I Am Currently Spinning 18x30 At 5400 With 8% Overdriven Gears On A 1983 302sr1. Looking At Possibly Upgrading Hp

That's a lot of wheel to be swinging! What speeds are you seeing with that bad boy?

88.9 Gps # On Flat Water, Poker Run Last August. Not Much In The Water As Far As Steering Goes. Sure Had Some Scratching There Heads Wondering What That Old Turd With A Square Windshield Was Doing Up Front. It Was Fun Anyway!!!!!!!!!! Am Adding Ponies But Conserned With The Steering. I Only Have Single Ram On Starboard Side , Like I Say Loose On Steering.

Check with Galen at Speedmaster. He showed me one he had there. I think that sixes and 3A props fit them. He'll know for sure.

I am running a 1987 311 with Kaama's and 375 hp. The drives are 1:1 with twin disc 502 tranny, props are 16.5 x 26 (I think, gotta check). Runs around 68, and handles great. I do have the newer Kaamas with the high mount for the trim cylinder and daul ram steering. I have always wanted to repower, sounds like yours runs great.
I saw a thread a while back about drive boots, anybody find some? Mine are good now, but just thinking ahead.

Nope, not yet. Apparently Archer Marine had a falling out with whoever was making them for him. I wish we could find out who it was.

How many rpm are you turning? That's the same size I'm using.

Mine has the dual ram steering also.

Just shy of 4900.
Have you had any prop problems, mine are original Kaama wheels. I keep hearing of guys loosing a blade. I have only sent mine out once to have them checked for cracks.

No problems yet, I don't know if they are the originals or not. I seem to remember the p/o saying he bought these, not sure though.

Hey guys,
Just wanted to ask River Rat if you have any pics of your 311 that you can share? When did you pick up your boat? Thanks......Al
