My Seacraft

[Vezo, Part II]

Tom, does your MA have the 70 gallon option? Didn’t you have an 18 originally, or is this your first SeaCraft?

I have only had this boat, and the tank is undersized, the owner I bought it from 3.5 years ago told me he had it replaced and that he chose not to go with a big tank. I suspect the tank is under 30 gallons size. When I pull it I will take some more photos. I am going to reach out to RDS and see how much it will cost to just get another one same size as this one. As I dont go offshore, literally stay with a mile or two of shore. If its too expensive, I may just Redneck it for now and run a 10 gallon above deck tank. Either way I will remove the fuel and pull the old tank myself.

I’m curious if RDS comes back close to $10/gallon. Remember you will have to choose between 0.90, or upgrade to 1.25 thickness aluminum. And then coal tar epoxy.

Some thoughts to consider as you address the fuel leak:
That is a pretty good pile of unsecured wires sitting/bouncing on a grounded aluminum tank.
At least one appears to be a large bat (+) cable; likely capable of carrying >>100A in a surge. Maybe 1/16" insulation?
Most small boats do not have a large circuit breaker/fuse on the bat cables.
Others wires appear to have open ends – not sure what they are.
Ever see what happens to metal when a hot jumper cable hits a grounded piece of aluminum?
Be safe.

About 15 years ago I replaced the 47 gallon tank in my Seafari with an RDS tank of the same dimensions. Seemed like a good idea at the time. Now with only lake use and with an ETEC which is not as thirsty as my Merc V6 150, almost wish I had gone with a smaller tank and gained storage area, as I never have the fuel hatch screwed done anyway. Just a thought.

On my 20 Sceptre, the tank would leak if I filled it to the top. It was leaking at the seal between the sender and the tank. How much fuel is in the tank? Before getting too crazy, I'd be tempted to drain it just below any of the outlets and let it sit again to see if it might be leaking from a hose or sender. If the tank is that new, I'd say those are more likely to be leaking than the tank itself.

Sage advice.

You have an original failed tank.
RDS is thick wall.
CG plate still on the tank?

I think I will have to run off a tank sitting on the deck for awhile. So the question for you guys is, how much runtime would a 6 gallon tank last? Obviously its a guesstimate.

Thanks for your input!

get 2 and dont get overly throttle happy
This will give you a rough idea of consumption rates at various RPMs if properly propped:

how come nobody is running plastic tanks under the deck?
