Fuel tanks

looking at my old knackered fuel tank which someone has bodged in over the years... Have no idea what capacity tank to go for!!! What would people recomend for a 200hp mariner. the kind of use is rescue and cruising somedays we could be out for 4 to 5 hours. Noticed i can get a 91 litre tank but thats the biggest i can find!!! Really want to get her on the water but want to make sure she's near enough perfect before we launch her!! Any ideas on under floor tanks? are these a real bugger of a job to fit or should i not even think about that!!

Regards

Phill

Your ocean should have a 30G tank under the deck.
My Suzi 200EFI does about 1.2l per mile cruising at 25-28Kn

Malcolm and Colin at Windsor Brothers Marine(Ocean) are reasonable people to deal with, and would I'm sure supply you with an original spec tank for you to fit yourself.

Fitting is not the big deal it sounds, just takes a bit of nerve to cut the deck, then a bit of work to make it look good afterwards. Remember the Ocean's are built like work boats, so will take a lot of abuse cutting and shutting the deck.

If you want me to go down and see them (I know them quite well now) I'm happy to get a quote etc for you.

By the way where abouts is your filling point for your underdeck fuel tank?

Windsor Brothers are in Porchester, between Pompey and Fareham.

The filler for my under deck tank is in the back of the passenger Jockey seat, along with its breather. The priming bulb is inside the jockey.

I've cut a section from an old and much larger image of the boat, hopefully you can see the filler in the bottom right hand corner.

Windsor brothers can be contacted on 01329 829100, although you might only get the answer phone if they are busy when you call. Tell them Simon Nash put you in touch.

Nasher thanks for the help finding the tank it is there however!!! All the pipes have been cut...... tank moves around a bit. Can anyone give me a clue on how to test whether this tank is of any use?? was thinking of a presure test or has anyone else got any ideas????

Phil Hi.

If its all been cut out it would point to there being a problem.


You'll get better access to it by removing the fuel gauge sender thats under the small round access hatch between the jockeys. Perhaps if the tank is moving around a good squirt of builders foam or similar with a long tube would hold it in place. As long as it never came into contact with any petrol.

If the tank is split or leaking it may not be the end of the world.
After your post the other day I have come up with a back up plan if mine ever splits or starts to leak.

As the tank filler, breather, and exit pipe all come up into the passenger jockey, my plan would be to cut out the deck under the jockey seat exposing an area of the top of the tank. Good time to use the foam as well.
A hole can then be cut in the top of the tank to give access to put a flexi-tank in through the hole.

Obviously cutting the top of the tank is a very risky business because of any residual fuel vapour, but this way the area of deck anyone will ever see is untouched.
The tank can be filled with exhaust fumes to avoid a big bang, but it would be best to get some expert advise on a better way.

Nasher.

good thinking on that one!!! Have removed some of the deck area so far!! so at least i know its there.... Only have one double jockey seat at the console so its a bit tricky to get to, just cleaning up the area around the tank. Boats in a bit of a poor shape at the moment one of those e-bay disasters, just spent a grand on the trailer, now braked twin axle, 1300 quid on the engine, just got to get the fuel sorted then hydraulic steering. Looks like im going to get the hull painted then decide on the tubes as some areas have been repaired. But hey at least i know everything will work after that, looks like its going to be a wasted season but at least it'll be right!!

Funny that, my Ocean looked good on the surface, but I gradually realised it needed more work than I thought. It was 4 years old and had really been abused.

I wasted most of a season and ended up gutting it. But as you say, I now have a much better boat that I know every part of well enough to have a go a fixing on the beach or at sea.

As you've probably realised by now they are built like the preverbial brick outhouse, but the finishing needs some work.

I'd have a good look at the wiring before going too far with it.

I've also just twin axle'd my trailer with two new 1300kg axles that I got a good deal on.
