Another 1987 Prostar comes back to life

Hey All,

We have always enjoyed slalom skiing, but the last several years our young family had gotten more into wake boarding and surfing. We ended up with a 2013 Malibu 23lsv (sorry team!) that we love. The only thing we don't love is the ski wake it throws. Rather than attempt to find a boat that "does it all, just not anything very well", I decided to bring the 80's back and buy a proper ski boat. I found a 1987 that runs and lets us ski right away, but is in dire need of some TLC. I picked it up for 5k. It has 1200hrs, the 351 and a velvet drive 1.5:1 tranny. Didn't know those existed?? Anyway, put it in the water for the first time this weekend and noticed that it takes on water at a rate more than I would like. The shaft seal definitely needs repacking since it drips at least every 1-2 seconds even when sitting still. When I got home, I tipped it up the nose of the boat and filled the bilge with water to check some of the seals in the transom, and this is what I found:

Port side:


Starboard side:


On the port side, the water seems to be coming from behind the through hull. On the starboard side, it is coming out from the exhaust itself. I am assuming the water out of the exhaust is left over from the weekend, would that be a fair assumption? When resealing the through hull screws, would I need to get the whole through hull out or would it be worthwhile to just reseal the screws first with some 4200? Looking at the through hulls, I'm not sure I can get the exhaust hoses off without removing the gas tank. Any suggestions?

I will add some more pictures soon. My plans so far include:
New battery (this one drops to 10v when starting and doesn't feel too strong)
Reattach rub rail where it is loose in places
Refurbish teak platform
Replace broken corner windshield starboard side
Repair and refurbish gelcoat
New decals
Electronic distributor
Trailer work - new lighting, clean and paint, new wheel bearings

Any thoughts and recommendations are greatly appreciated. Thanks Team!

As promised here are some pics:





I've tightened the shaft packing and resealed the exhaust. Going to the lake this morning to see how it does with leakage. Any tips on what I else I should be checking in an older boat would be much appreciated! Thanks Team.

Just got to the lake to check the leak situation:



Yes, there are a lot of local fires this year. So far the crews and bombers have done a great job!

It looks like I have a couple of trouble spots:



1: the starboard silencer is leaking, it appears to have a hairline crack in it. Where does one go for parts, in Canada?
2: the shaft seal is much better after adjusting. There is still water coming in from under the rubber hose, even afer tightening the hose clamps there. What is that magical hose covering?
3: sadly, if you look closely, there is also water coming in through the fibreglass hull just beside where the shaft goes through the hull. Very little comes through here, but what would be the best way to prevent further problems there?

I suspect that I will need to pull the prop shaft, assess and repair some fibreglass and then replace what is under the magical rubber hose. Sound about right? Forgive my lack of knowledge, I know my way around cars very well, but for some of the boat related items I'm still in learning mode! Thanks again for all the help.

Can get fibreglass repair kits at local canadian tire. Do you have any vibration while under power? That prop looks chewed up, might be the reason you have a crack where the prop shaft goes through the hull - possible the previous owner hit something.

Yup, the prop has some character marks on it, but the boat is very smooth. No vibrations at all. She still skis like a dream, especially compared to the 23lsv!

Okay, potentially stupid question. Given that the silencers look like they are fibreglass, can one patch those temporarily allowing me time to get through this year and tackle proper replacement over the winter?
