Pete7 you were right in saying that we were discussing the prons and cons of SS tanks Vs plastic. I am still not convinced that SS tanks are any better than their plastic cousins.
Gavin 55 ltr plastic tanks will not be sufficient (I have a 200 bhp VMax F2 modified on the boat) which in full throttle drinks like mad more than a Honda 4-stroke 200 bhp (I was told - so don't come bashing my head about that comment LOLOL
AP as you know due to the very light weight of the boat and the amount of petrol I'll have to use I will have to fit SS tanks.
However, I'll fit them on deck rather than inside the hull one forward one aft so if anything goes wrong to be able to repair them quickly and without major surgery on the deck (thus avoiding to compromise hull integrity).
In any event I would need to see how much these tanks cost in this country and whether anyone knows of a reputable SS tank manufacturer who can help
