If you've still got it after I've got the boat set up as I want it I may swap with ya mate.

However if you plan to change the consoles around then you will want to put as much weight up the sharp end. The flooding hull is only at the back end which is just were you don't want it so couple of corks and a tennis ball should block the hull up nicely so you get a chance to see what it handles like without the flooding hull.

Had a Yam 115 on an Osprey 5.25, feck it was quick with 17" prop and quite able to throw you off the back of the console. Only tamed it by putting the engine on a 5.95 Osprey. Superb engine though so look after it carefully. I still have a spare stator and coils if they play up btw.

It's is over powered but, but, but..........
Sounds daft but I'm not a speed freak. I likes that engine though.
Now you've said that about the water inside the hull being at the back it makes sense due to the shape of a hull.
And I hope I never have to buy those bits of you but keep them safe please

thats a hell of a torquey (is that a word) old lump to hang on the back of that boat, i think you need to put a lot of weight just fwd of midships for balance, imo if you put it to far fwd it may tend to stuff, my only concern is that you will kill yourself before you get it right, go out again with a few people and move them around in the boat to see whats best, and if you do kill yourself can i have your boat

Looks like you have the holes for the stop bar but don't have one in there.

Was worth a look.

Thanks Biffer, you have a heart made of marshmallows
One good thing about Knott end slip (on the right day) is you have the calmer river to try things out and then nip into the channel to try it out on lumpy stuff. And if all goes to wrong, beach the bloody thing.

Right, just a thought. If I was to gut the deck and place console, seats etc in and a weighted box to act as fall fuel tanks then move the axle on the new trailer, I need to get, to find the rough balancing point (see-saw style) and then mess about with arranging. I should get an idea?

Buy some more fuel pipe and put the fuel tanks in the bow. You'll be suprised how much difference it makes.

Completely different but my Longliner would ride bow up, too much throttle I know. Put some shot blast grit in the bow and it was fine.... hit the first wave and it went through it rather than over it!

Think I paid 8 for a bag of grit which weighed roughly 30kg.

Have fun,

Phill

from your pic i'm guessing the weight need to be where you stand, if you could rig your battery and fuel either side of where you stand that should help a lot, jam the fuel between your legs as i'm assuming the battery is in the seat, take a couple of bodies with you and get them to hold on eitherside of the console, if thats to much move them either side of the seat pod and so on

The fuel tanks are meant to be under the console and I know 2 25l tanks are heavy. Will use some people like you and codders suggested. Just would like to get a good idea of where to have the other console tanks and battery.

The plan was to have one big fuel tank inside the new console, with a partition inside the console so no electrics could spark of a heated relationship with any fumes. And then move the double Jockey up behind the console and keep the battery in that.
