..... Anyone that has or had this setup what was the clearance issue, was it the heat exchanger expansion tank? Was it the valve covers? You'll have one major issue. The height. You'll need to chop the step up deck and raise it some 4 or more inches. Also your port expansion tank will bump into the...

At what HP? I was also thinking that 150hp was pretty light for a hull that has similar weight and dimensions to a 31. It's just at the limit. The boat needs to be pretty light. Bimini vs. hard top No tower etc. In NC waters, most of the time you can't run a 28 much above 20 knots w/o getting beat ...

The 4BT's (CPL 741) put out
130 BHP for medium continuous
150 BHP for intermittent

I ran a 28 with 4BT's for five years.
No tower or genset.
It would cruise 20+ knots all day long.

Mike,
I think that was only a problem on the 4B 250. The Bosch injector tips were a problem and they tried a number of solutions.

If you use the Barry mounts there is very little vibration transmitted.
The 4BT is indestuctable provided it has the new stlye heads and is never
overheated. It has a very small expansion tank. I'd love to try the 4B 250 in a 28.

The lines in the picture are Aeroquip.
The fittings are not crimped on.
The are screwed on and can be reused.

The ladder is on the flip side too.
Anyway I don't see how duirng backdown the scuppers would allow that much water in. They aren't that big.
Plus there should be 3 bilge pumps on that boat.
I suspect some bilge pumps were not working.

I've got a lot of experience with 4BT's in 28. 1.The solenoid in the CAV pump needs to be charged for the engine to run. The 12V pull the plunger back. The plunger can be removed and you can use manul levelr to shut off. Usually there a swicth on the dash to energize the ignition ciruit and the plun...
