I really like the looks and features of the sr1 formula boats. It seems to be an uphill battle to find one with a non wet fuel tank foam that eventually causes rot and other problems in that area. Finding one that is repowered would be nice too. Maybe I should just move up to a fastech formula to get away from some of these issues? I'm open to any educational advice.

given that those boats are 25-30 years old, it will be hard to find an SR1 (1987 - 1991) series without some moisture issue, unless it has been re-built recently.

Even if the engine bay is kept dry, condensation from daily temperature changes puts moisture on the tank and it slowly works it way down through the trimmed foam around the tank.

Maybe if you find a boat that has been stored in a heated building its who life, but what are the odds of that?

Hmmmm - I am on the edge of selling, but I may have what your looking for.

how can you test for moisture in foam around the tank on that boat? isn't the foam locked in between the stringers and bulkheads? i.e. wouldn't you have to pull the floor up?

the 'best' way may be an infrared camera. With a little bit of access you could take a core sample from the foam, but that is somewhat a 'destructive' test and would not be done as part of a survey. Checking the lower part of the engine room bulkhead for elevated moisture is another way to check.

So soon????

Seems like you could pick up an older sr1 and have the stringers done for less than what some of the turn key fast techs are going for.

Mine is dry.

How much $$$$$ would the cost be to replace possible corroded fuel tank and surrounding rotting stringers on a sr1 311 approximately???

$8K . . . approximately.
