Hi,
I have twin tamd61a and ZF220a gear box’s. my starboard engine and box have been fine no problems at all but the port one has a couple of problems the first being an over heat at high rpm so have changed impeller and that’s not fixed it, so will be striping coolers and exhaust elbow to sort it.
The second is that on the same engine once started from cold the preheat stays on on the dash panel but the starboard one goes out as soon as engine is running.
The third and final problem is the port side gear box has what sounds like a noisy bearing, I can only hear it when in forward gear at over 1000 rpm it’s not there when in reverse or in neutral, cold this be linked to the first problem and does anyone have any ideas on rebuild cost of the box?
Ps these problems have been there since I got the boat at Easter.
Thanks Luke
