Fuel Tank

So I am still looking for an outboard around 40 to 60Hp long shaft 4 stroke..

 

What size fuel tank will I need in gallons please (I'm English, to old to think like a Euro)

 

Well, if and when good enough and safe enough to do some of the wrecks around 10 to 12 miles out.

Haveing not seen many filling stations out there!.

So going out 12 miles moving around and getting back with a gallon still in the tank would be good,

a little more fuel even better.

 

I have seen some tanks with male electric plugs fitted to them! Is that some sort of pump?

I doubt it is, but if you don't know then ask. 

 

My Mrs thinks, asking question like this that I will look a prat. But I think I would look a bigger prat

going out and then finding out the hard way.

I completely agree wirh you John.

 

I don't have the experience of different boats & engines so others will probably be able to input.

 

Most importantly - - - - - - don't go anywhere without a buddy boat or three until you're used to your boat. The weather is begining to change now so there should soon be a few of us about.

 

As for fuel consumption - - - there are quite a few threads on here regarding spreading the weight on the boat - - - choosing the correct engine - - - choosing the correct propeller for your engine etc. etc. etc.

Are you sure you haven't been smelling the petrol fumes?!!!! :)

 

In all seriousness, no one cal advise you with such little information.

 

4 stroke, 2 stroke, new gen 2 stroke will play a part. You then need to think about the conditions, you could use 1/3 more fuel coming back if the sea kicks up.

 

You need to spend some time inshore to get to know the engine you are yet to buy. One of the members with a 225 had an issue with something or other 25 miles out, on the way back he was burning so much fuel than usual he nearly ran out. He had no idea until almost too late.

 

Not sure what you are meaning re. pumps on tanks. Wait till you get an engine, the tanks are cheap enough to buy new / newish so you can be sure they are not contaminated.

 

Just get to know the rig, then worry about heading out!

 

FYI, I have a light rig with a 50 4 stroke, I usually go out with a 25 and a 12 litre tank.

 

Charlie A has a relatively heavy Shetland with a new gen 2 stroke 75 and often carries 50+ litres.

 

(4.4 litres to gallon btw!)

 

Just take it easy get to know the boats reliability and quirks inshore, the, as Jim said, venture further with a buddy boat.

When I ran my Warrior 165 with a 60hp 4 stroke Mariner, I used to carry 50l, about 11 gallons. I used just about 0.75l per mile so this gave me about 60 mile range. When wrecking mid channel, I used to take an extra 25l.

 

Outboard tanks will have one of maybe 3 or 4 different connections on them. Provided all your tanks have the same connection you can simply unplug and switch tanks, this saves decanting fuel at sea.

 

I'd suggest you need minimum 5 gallon (25l) tank, ideally 2 of these.

 

Hope that is helpful.

As a safety rule of thumb you can travel 1/3rd on the way out, 1/3rd on the return and a safety margin of 1/3rd in reserve.

 

Many people use 3 x 25ltr tanks so they can use up a tank going out, a tank to come back in and a tank full in reserve.

 

However the distance to will be able to travel, as Rob and others have mentioned, has many variables i.e. tide, wind, sea state and weight.

 

Best suggestion is to carry out some fuel usage trials when you are set up in both good and poorer conditions so you get some idea of usage.

Most plotters will show distance travelled, which you can re-set for each trip, fill up your fuel tanks and go for a trip. On your return note the distance travelled and re-fill the tank(s) and you will quickly build a picture of your fuel usage.

 

I use to keep a log of all my trips in miles and fuel used, it also helped to see if the engine was developing a problem if the fuel usage rose for an unexplained reason.

 

Oh I nearly forgot, cycle the fuel tanks so the newest tank full is always the last one to use. 

 

Hope the above helps

You are right I should have given you more info. If you look at   Is this a Norman   (just below on the listing) there is a photo of me boat.

I can only go on what I have been told and that is  I will need a 40-60hp out board Mariner / Mercury as that is what has been taken of only the one that was on her was 115hp Mariner.

 

I was told to go for a 4 stroke as they don't use as much fuel. and I will need a long shaft.

It is the fourth one down under Fuel Tank  Is this a Norman? (this is not a link, mind if I was able it might have been)

No, it is the fourth one down in the list of topics.

 

Why half the size out board? Well, he had about 6 or 8 bags of sand in the bow to keep the front down and it was well over powered.

"I was told to go for a 4 stroke as they don't use as much fuel. and I will need a long shaft."

 

It will depend on the age of the motor - the new Direct injection 2-strokes (Etec - Johnson\Evinrude  or Optimax - Mercury) are comparable to 4-Strokes on fuel efficiency.

 

The use of fuel will depend on the hours you intend to do - if you will only use it for 5 trips a year and an older style 2 stroke will use twice the fuel of a 4 stroke (50 gallons v 25 gallons or £300 v £150), but costs £2k less - it might not be worth buying a 4 as to save the difference (+ more servicing costs of a 4) woudl take 13 yrs to pay back!!

 

Why- those kayaks look good value!!!!

Have you checked the transome for cracks / damage ?
