I couldn't fit the boat in the garage without removing the
swim platform, so I had to buy or make some removable mounts. I made several attempts
to contact Alloy Marine to get a custom set of brackets made but I never got a
call back. So, I decided to make my own using some stainless flux cored MIG
welding wire. Also I had to make a swing away tongue for the trailer to fit as well. |

Then I cleaned the engine cradle and coated it with 2K SprayMax high gloss epoxy. I also drilled and countersunk 1/4-20 stainless flat head bolts through the cradle so I could attach fuel lines, wires, steering and throttle cables etc. While the engine cradle was out, I poured Restore-Rite StongBond Epoxy Wood Sealer into all of bolt mounting holes in the stringers. Then when I reinstalled the engine cradle and used 3M 5200 in all the holes. I also sanded the gas tank boards and applied the same wood sealer to them before I resinstalled them with new stainless hardware. I installed a new blower, blower hose, new gas tank filler hose and filler port and wired everything up. Also I bonded the gas tank filler port to ground.

I also stripped all the black so-called epoxy from the entire bilge area. In the process I realized that some of the fiberglass was delaminating from the wood substrate at the corners where the floor meets the exhaust channels. I decided to cut the fiberglass out and just address these areas. I know there is some wood rot going on the exterior stringers, but I was not ready to do a full stringer job yet. The main stringers seemed to be in good shape, so I proceeded just fixing these areas. I cut out the old delaminating fiberglass and covered with 3 layers of biaxial 1708 fiberglass cloth and Isophthalic Polyester Resin which after reading on this forum doesn't seem like the best choice...but it was already done so maybe next time lol. After I was satisfied with the
fiberglass repairs, I finished stripping the bilge and I applied 2 coats of
Total Boat Bilge Epoxy.
It went from this:

For the exhaust manifolds I spent hours sand blasting these
things. They were so rusty! I also resurfaced the mounting surfaces. I powder
coated them and then stripped the powder coat on the spots that attached to the
head and receive the most heat and coated them with KBS extreme temperature
primer and paint inside and out to hopefully deter some of the rust for a while.

I sand blasted and powder coated or painted anything and
everything I could including the engine mounts, transmission, transmission
mounts, new Edelbrock intake manifold, steering cable arm and bracket, timing cover, all water pump/thermostat pieces etc.
Nothing was left with the original paint. I even went as far as taking the
alternator apart so I could paint the housing black lol.

Machine shop bored and honed the block, installed new cam
bearings, resurfaced the rods and the crankshaft, and sold me new pistons,
rings, main bearings, and rod bearings. I ordered all the marine gaskets, new oil pump, ARP oil pump shaft, rear main seal, a blue one piece rubber oil pan
gasket, new RR Pertronix distributor, new water pump, new impeller pump pulley(because
I damaged the old one), new impeller, all new hoses, new elbow hose fittings
for the exhaust manifolds, new 160 degree thermostat, new coil, new plug wires,
new plugs, new Edelbrock Perform RPM intake manifold, ARP bolts for everything
I could get them for, Holley Sniper EFI system, new starting relay, and a new
alternator. Was rustier than I was expecting but I spent some time after this picture with a dremel and a sanding disc to clean it up.

I pulled the motor out to check the condition of the main
bearings and all were in pretty good shape except the rear. It had significant
scoring as well as the crankshaft for that bearing so off it went to the
machine shop. The carburetor was not rebuildable either. Intake manifold was
full of rust on the inside and not usable. I also found a broken tooth on the
distributor.

The hull was in great shape, the gel coat/exterior looked good
for the year and the interior was almost flawless. The carpet had been removed
and the PO had sprayed this so-called black bilge epoxy everywhere inside the
boat which I realized later was NOT a good thing. The motor was a big question
mark too, the PO knew nothing about engines. The marine shop he took it to had
pulled one of the heads, not sure why but the PO ultimately decided it was too
much money to warrant the repairs and decided to sell it. Lots of rust on
anything metal as well.

This topic has been something I've wanted to do since I have substantially completed my project but I have been waiting to create it until I could organize all the photos and consider the best layout. After much consideration, deliberation, and delay I figured I just better get on with it lol. Thank you to all those who post on this site and help the newbies. I am on this site regularly lurking in the background, soaking up information and I learn something new all the time. I can honestly say this site and those on it gave me the knowledge and confidence to complete this project. I know there is still a lot to learn about these boats but with this site I know about 1000% more than what I did when I started. Cheers to all of you! This topic is about my introduction to Ski Nautiques and my journey to restore the boat I ended up buying that I wanted to share. I have always loved boats/boating/tubing/fishing etc. I
previously had a 1984 Bayliner Capri Cuddy Cabin which was in very poor shape.
Mechanically it was pretty good, but the floor was rotting, the interior was in
poor shape etc. The wife was always worried about taking it out with irrational
fears (or maybe not so irrational) of it catching fire or sinking, that’s the
kind of shape it was in lol. |
