Need help rebuild

Hello. I have a 1969 correct craft, I need some help/ advice on motor and trans rebuild/replace.   Is anyone, we'll versed in these boats drive train, willing to be a sounding board while I work through this process?   TIA

Ok. I bought this boat about a year ago.   It had a bad motor.   I had a shop replace the motor. He replaced motor, with a standard rotation motor, (the boat originally had a reverse rotation motor) and "flipped a gear" in the transmission to make the boat go the correct way when in gear.   When I got the boat back on the water it ran great but the transmission seems to be slipping. I posted this one last year and received some good info.   So now I'm trying to figure out the best way to address this problem.   
Options :
Rebuild trans "as is" with reversed gear, and will that work?
Rebuild trans back to original and replace Motor with reverse rotation motor
Replace trans and prop with standard rotation equals
I think this boat is a Freeport model.
Motor is a 302

A Velvet Drive trans always has to turn the same direction as the engine. If they kept the same propeller that was on the reverse rotation engine then they were running the trans in "reverse" to go forward and putting it in forward to use reverse which in case the trans won't last long. You can set up the trans for the left hand engine but you must use a left handed prop. In a Correct craft ski boat it is frowned apon to use a lefty engine since the hull is set up for a righty. Don't know if this applies to a Freeport since they are a v hull rather than a flat bottom.


Rebuild trans back to original and replace Motor with reverse rotation motor
Best option it will then work as the manufacturer designed but more money will need to be thrown at it

Replace trans and prop with standard rotation equals

Theoretically you can. Don't know what your skill level is and I'm not sure about your mechanic either. You would need a complete rotating assembly,302 flywheels and harmonic balancers come in 2 different imbalances compared to 351's and you would need to know what your doing.

Sounds as if your mechanic had the trans running in reverse to get it to go forward when you put it in gear when you were driving it,do you push the throttle lever forward? Put it in forward then go back to where the cable attaches to the lever on the transmission. Is that lever on the trans now forward or is it to the back? Maybe have someone move the control lever while you watch the transmission lever-- Control lever forward trans lever should be forward, Control lever back into reverse,trans lever should be to the rear.

Link to Rene's previous thread about same issue

previous thread

Is the boat accessible so that you can put the shift lever into forward and then go to the transmission and see what the position of the lever on the transmission is like has been suggested by Gary.

That will tell ya' a whole bunch

The lever on the transmission should be angled toward the front of the transmission when the shifter is in FWD and angled toward the back of the transmission when it's in REV.

Otherwise like Gary said the reverse portion of the transmission is being used to drive the boat forward and the forward portion is being used for reverse................and it ain't gonna last long

A Borg Warner 71C has the same 1 to 1 ratio in FWD and REV so if this thing really is using the reverse clutch to go forward it'll go just as fast until it starts slipping or just dies completely.

A 71C has 5 forward plates and 1 reverse plate so forward can handle a lot more load without slipping
