3.6mtr bluefin

[Next Up]

Hey guys recently bought a 2004 bluefin with a 25hp 2stroke yammy, the transom has been reinforced to cope with the heavier motor. Anyway the issue I'm having is it porpoises really badly over about 35km/hr, it's fine on flat water but any chop and it just get worse with more speed. I'm new to boating and just wondered where I should I start to try and sort it out. Could it be as simple as weight distribution as I'm around 110kgs and most of my passengers are 30-50kgs lighter than me

Boats a very simple set up, two seats one 25l fuel tank down the back, anchor and chain upfront, maybe 10-15kgs of fishing gear, Generally only fish two up and no ice or esky or bait tanks etc

Any help appreciated

Try dropping the pin height on the motor 1 or 2 holes. Just keep playing around with it till it gets to what your happy with. If you can you could try put the tank up the front. This might help.

I had the same problem with a 375 explorer. was told to lift the motor an inch or two as it was too low in the water. put a wooden block on before you put the motor on to lift it out of the water . Regards Howard.

Sounds like you need more weight up front.
