Searider 4m large fuel tank to fit under front

[Dino89]

has any one fitted a large say 50 litre + tank in the front of there searider
would like to do this for to reasons one it would add to the weight at the front and help keep the front down and on a four hour trip i have to change tanks at present to 2 X 25L tanks
is there a tank that would suit this purpose attached a photo of front to give idea of space layout etc

I had a twin set up in a 4mtr S/R,both plastic I think Plastimo,(standard size 25ltr) the one in the bow was triangular which fitted well.

I fitted a change over toggle switch between the seats to avoid flaffin about

I realise this dosen't answer your question however maybe you don't need a larger tank.

mileage with a 60hp merc 15" prop two chubbies bits and bobs approx 80 nm.

It was a 92' two stroke, the large pitch prop meant 30 mph 1/2 throttle.

full throttle would eventually turf you out the boat.

thats something to look at mines a 50 merc 2 stroke could look into a different prop not to worried about top speed would like better economy

I konw increasing hp is the wrong route if your looking for better consumption figure but...I'm fairly sure depending on age,the 50 only has different jets in the carbs? someone might be along any min now to say thats bollerks.

The extra torque might be the reason my engine could swing a larger prop.

Might be cheap way of achieving the goal

if any one has any info or thoughts on jetting the carb its a 1999 50hp merc electric start would like to hear
or even changeing prop

Nah, it's not just a different set of jets. I think the carbs themselves are different too. Upping the jet size will just make it run rich.
