Mike, we never heard of a Mayflower 48 having a fuel tank
They are cast iron.
Ours are forward of the engine
bulkhead. As you open the cabin sole hatch
you will seen them on the port and starboard sides. They have very large inspection
plates. So, you can remove the plate and see the inside of the tank and use he large hole for cleaning
. The tanks are supported above the bilge
for protection. We painted ours gun metal gray years ago and the paint
still looks good. They have never been stainless steel
. One thing to look for is the bonding wires on the tanks. In fact, it would be a good idea to disconnect the bonding cable on the port side of the engine
. Then turn on all of the lights and electronics
to check to see if any of them stopped working. If so, this would mean that someone used the bonding system as a ground. If this happened to the tanks ... it could explain the rusting or corrosion
Another cause could be water
in the fuel rusting the tanks. Mayfower 48's have transfer valves. So, its a good idea to move the fuel between tanks to keep the fuel clean. Assuming the yacht has a very good fuel polishing system installed.
You didn't say if the bottom of the tanks were flaking or the tanks were leaking.
There are two 75 gallon fuel tanks on the Mayflower 48. There are also two 100 gallon water tanks. We converted one of ss water tanks to a fuel tank
. We will take a few pictures and add them to our website at ahawaii.com/jamtlander
An earlier post claiming that single
spreaders on the main was a weakness on the Mayflower 48. We have no idea where that came from except...
We can tell you we had a knockdown going into Roratonga in 25 foot seas and were hit by a rouge wave of unknown heights. We have single
spreaders. The Mayflower took the knockdown and every thing came up in one piece.
Also, the earlier post claimed that Mayflower Yacht were owned by a British Company. Not true. Only three Mayflower's were sold to a UK company. The first batch were sold to Mariner Marine
in Long Beach.
of Long Beach California
named the yachts "Mariner 48".
The were Hulls 2, 3, 5, 7, 8, 9, 11, 14, 15, 16, and 17.
The rest were sold to small dealers in UK, Italy
, and the Bay Area. The rest were sold mainly to individuals after the word got out that the Yachts were of very good quality and performance.
Hope that helps.
P. S. the name of the yard that built the Mayflower 48's was:
May Flower... not Mayflower.
