Ha yes... perfect if you have the standard 25l tank that usually comes with a Mercury/Mariner 2-stroke as it's able to hold the floor into some reasonable shape being a close fit under the seat.
This is interesting stuff. Do you think that Stormsure would be suitable for a tiny pin prick leak on an Avon SIB? It is made of hypalon. The leak is on the underside of the port tube so much lower pressure than an Aerotec floor. Or am I better off going down the patch route?
Despite the total success of the Stormsure had there been sufficient room around the hole for a patch that's what I would have used. But you've nothing to lose trying it as it could easily be cleaned off to put a patch on later if it didn't work.
