you could rev the right with no more speed ? How bout the port ? ..... to me ....its gota be a) coupler b) hub c) clutches...

Exactly.
Port engine will move the boat faster
a) changed the coupler
b)changed props 3 times including turning them in and out.(28" and 30" Bravos)
c)threw a spare drive on the right side.
d)examined the bottom of the boat.
e)removed speedo. pu since it's on that side.


I'm seriously giving thought to swapping engines and drives right to left. This will determine if it's mechanical or water flow to the prop , but man , it's prime season here now and i don't feel like going through all that...

Sure sounds like the coupler to me, only you should smell rubber burning if the coupler is slipping.

You're right Joe , I agree , but I just changed it the wednesday before July 4th for the same reason and it made no defference.at that point I did have some rubber in the bilge. I also asked a friend who is a Merc mechanic if he ever saw a "bad" new coupler and he said not in his 20 years experience. He DID concede he has see other new parts bad

you need to talk to someone that knows the drives .....I am not sure if the clutches can slip .....or Swap Drives .... thats got to tell you something ...cpl hours of work .....

I already put a spare drive on the right but before i get too crazy I am gonna swap drives left to right. I KNOW the left on is good

I know this is real simple, but You do have solid hubs in those props, right?

Did props get mixed up somehow? make sure they are what you think they are. I fought that for 3/4 of a season before I found that out once.

I have a set of 28" and 30" bravos with Flo Torq hubs. Tried both sets and new hubs and even swapped sides (tops in instead of out)
