    Blackhawk smooth shifting!

    Tested this mod on the bh drive over the last season. What I have done is created a resivior of oil in the shift chamber. I fill it with hi perf merc gear oil. So the shift slider and drive shift mechanism all rides in gear oil. I have found that the oil lubes the cable as well. In the pic there are two holes dlilled and taped with drive oil plugs. One is used to pump oil in the other a fill vent.

    Thanks! My 9 yr old usually takes the pics and he was at school so I struggled through. I was getting the boat ready for the season and was filling and checking and thought this mod may be of interest. The same can be done with a bravo but the plugs would be in the rear shift cover.

    As you know shifting the bh can be a bugger. Just made everything feel a little smoother. In my case reduced the stiffness.

    Muskoka meeting

    I'm looking forward to meeting you, seeing and learning from your work. I've got a 22 under renovation. My bravo hi perf drive has a shorty on it with some internal work. Steve from sterndrive connections in Orrillia did the work. He's told me, if I don't play nice, I'll still break it.

    The motor is a Procharged 540. Any mods that toughen it up, within my finances, will be useful.

    Wow Fred, that sounds like a powerplant. How much boost are you running and what hp are you expecting?
