I need some advices on what to do or what do you think about that... I did a fresh air exhaust system on my sunsport 87 last weekend.
When we remove the exhaust cover and the plates screwed to the transom , some water start to drip from the bottom screw hole... not a lot but a slow dripping and when i push hard on each side of the bottom screw more water come off.
The starboard side is really the worse and i think i have a story for that :
I bought the boat last summer and had heating problem due to the raw water pump hose that was mostly block by parts of a destroyed
impeller of the previous owner :shock:....(he put a new impeller when he sold to us so). All this reduce dramatically the amount of the cooling water flow obviously. One day everything went really hot and even before the engine temp went high , BOOM ,the big rubber exhaust hose blow/melt and some smoke was coming off the floor and
from the stainless pipe of the same side. we drove back to the dock and let the boat a couple hour ,went buy a new rubber exhaust hose ,came back and the boat was starting to flood (water at the shaft level), took the boat out of water onto the trailer.
After several minutes of troubleshooting on what did that... we found pretty much a complete impeller in small pieces in the raw pump
hose so the heating and cooling problem was from there. But the transom (still on the starboard side) was kind of soot up. Exhaust cap
and plates remove and the seal arround the stainless pipe was mostly disapear/burnt/melt and even some gelcoat was missing :eek:...
We did a that moment a bit of gealcoating to fill up the small part missing and a big fat sealing joint arround the pipe and behind the
exhaust plate before screwing it back in place.
Since and after that ''repair'' no more water was entering the boat and the cooling was good untill i unscrewed everything to make the
F.A.E. !! now i have a new suprise and i'm pretty sure that mean the foam in the haul is soaking wet !!! I hope it's only that and the fiber
glass did not absorb some water if that is possible.
I want to use the boat ASAP and dont have time and especially the money right now to rebuilt everything.
I thought i could open the floor under the back seat , get access to the transom and the exhaust pipe by the inside , maybe i had to tooksome of the foam out and make a good high-temp silicone joint arround the pipe . I know this will be a temporary fix just for the season
(here in Quebec boating season is really short not much more than 3 months). Next autumn we plan to start real rebuilt...
SO NOW WHAT SHOULD I DO ?? Thanks a lot for your advices !!
