Hi,


I have a leak behind my observer seat. Every time it rains, i get a good amount of water on the carpet below the glove box. it seems that the water is dripping from the port side wall.
what are the common cause of leaks in that particular place ?

also, is it a tough repair the spider crack under my pop up cleat ?

for the leaks, i suspect 4 things.

The gasket under the tower mounts .

That looks like a good point using silicone rubber sheet that wont degrade.
The marine urethane sealant is nice stuff that comes in color choice and very tough.

Resetting cleat with the same sealant should work also.
Micro cracks in jell coat probably are not the cause of leak.

The vent has vent tubing that goes down to feed air back to the engine (I guess that's what it is for). Put it in a container and the next time it rains if the container if full that answers the question for one of the 4 area's.

WOW, I have a 97 prostar 190, with not a crack in the gelcoat, if that was my boat i would be calling mastercraft for a repair, and if thats the quality now i'll keep mine and never buy mc again.

The water seem to be dripping on a glassed pipe that hold some wire. its not directly under the vent. i will try to dissemble it at put some sealant anyway.

I just got this boat used and it has 757 hours. i do not know what the previous owner did with it before. The boat is in good condition except for theses cracks, rub rails will need to be changed (its gray and has an impact mark), also i have 2 two of theses that need to get fixed and finally 3 skins that will need to be changed next year.

this boat is a huge upgrade for our familly. we come from a Maristar 1995 225.

I would say your water problem is most likely due to the windshield gasket. This looks like a pretty big gap an a place where the water running off the windshield could go. the other places are less likely to get an appreciable amount of water on the carpet. Can you push the windshield gasket back in the groove/ Nice boat.

depending how it sits on the trailer- could be coming in the holes in the cover around the tower.. Mine does that depending on how tight I cinch the cover, and how level it sits...

Get a hose and spray it over each suspected area (one at a time) until you find the leak. I tend to agree with Mayo as it would take a lot of water/rain for it to be the tower and/or cleat. My bet is the air intake (crack in the pipe leading to the engine compartment) or the windshield.

Vent Tube! I have the same problem if the hose gets old and cracked. Pull the vent tube and inspect...

If it's the duct behind the vent and it's the same as mine it's 3" diameter and you can get it from SkiDim by the foot. I'd check the rest of your tubes because they're likely equally hardened and prone to cracking. I replaced all of the pieces for the blower and the rear vents because they had gotten really hard. I hit 2 of them with the pressure washer and they blew apart.

I will take care of this gasket tomorrow morning. after i will do the water test as bobx1 is suggesting.

i have an appointment in two week with a shop that will fabricate a skirt for my cover. They will also stitch some 'collar' on the cover where the tower mount goes. it will prevent water from enntering the boat..

May have to pull it out first warmed up to apply sealant.
A rolling tip tool found at body shop supply will massage it back in.
