I have a 95 crest 25' pontoon with a force 70 outboard. It has been giving me fits running well then leaving me stranded after a cool down. Thanks to Roscoe, today I am replacing some questionable parts and wish to do a decarb of the engine with sea foam deep creep. Question is, i have acess to a boat ramp into the Ky river that sees little use. Do you think I can safely run the outboard on the trailer while applying the cleaner,pull it out, spray in cylinders, let sit till tomorrow, then run at wot for 15 min, pull out and change plugs. Would be so much easier to keep the boat on the trailer as all i would have to do is pull forward to access the pluge etc? Boat would be tied to trailer with four rachet straps and hooked to 3/4 ton chevy diesel truck. Would you think it safe to potentially run the boat at wot while on the trailer? She's no powerhouse speedboat, but will cruise at 15-18 mph. The ramp allows the engine to be fully submerged while still on the trailer. Another reason is, if the boat were to strand us again i fear my woman will set it ablaze.lol So maybe I can duplicate the conditions that have gotton us stranded on the trailer without the risk of the butt-chewin if the boat isn't fixed. Anyone have any experience running a pontoon on a trailer? Thanks so much for your help
