Adding more Bouyancy

Anyone enclosed and sealed up their outboard motor pod?

It would need a water tight hatch  to allow acess to the engine mounting bolts, but i think its a simple way to add some extra  bouyancy to the stern of an aluminium boat.

Absolutely.Easy way to test..Grab some polystyrene - I bought a sheet at bunnings for about $30.00. Cut it about the right size or a tad bigger and just wedge them in to the height you want. A bit of water will still get in but 1/2 a litre won't matter. Holds the stern of my Bluefin up nicely........The joys of heavy 4 stroke engines.......

check out the fishing report, "Making a good thing better"  I think that's it from memory.




These new Evinrudes are frigging amazing, 25-27 knots using around 1 Litre of fuel per Naut mile. Shocked   

I admit to being skeptical about the new 2 stroke but after a lot of fishing trips  I would never  go to a 4 stroke, with the 2 stroke having around 200 less moving parts to let you down, being lighter and we all know the power a 2 stroke engine can generate. 48-50 knots is scary.

Only the once mate, I will say that a 6.4 pontoon chine walking is interesting.

Shit -not for me! Mind you, I wouldn't take a rig like that to sea anyway. In my head, that setup is suitable for a small lake or a blast across a small harbour on a flat calm day.

I agree, 
Mikes 6.4 pontoon KiwiKraft  "running light" during  trials (to find the right prop)  after he had done a few modifications to the hull and having the new motor fitted was able to reach speeds over 50knots, this was about 20-25 knots above its designed top speed.  Grin

Once it was finished being refitted, loaded as for normal fishing trips with four adults, Fish bins ice etc it cruises most economically at around 27knots using around 1 litre per nautical mile which is excellent for such a boat and load and has heaps more power available for dodging waves etc on bar crossings, I think it can reach around 40+ knots in a decent sea
