    Even though this was a one owner boat, it needs quite a bit of maintenance from a mechanical stand point. No matter where I look, I find more to fix. Here are a few horror stories to get the project thread rolling, but so far the work has been rather limited -

    I stripped out the dash and original DC switch panels which were over due for replacement. No surprises here. I removed both of the heat exchangers for inspection. The CAT unit for the motor will be cleaned, assembled, & pressure tested. The aftermarket cooler for the transmission will be scrapped and replaced with a CAT unit. As chance would have it, a crack in the prop hub was revealed when I took a random photo. The light must have been just right because it was not that visible by eye when looking at it until I pulled it off the shaft. Sure enough, the crack had originated at the key seat. Removal of the cast iron exhaust elbow (which is a BAD idea to begin with) revealed that it was original from 1981! So it's no surprise that the turbo looked like this. I was told that the motor was actually converted to marine use when it was new and that this might have been overlooked. Kind of shocking to be honest, but not with my luck. Ha ha. So I have a new bronze CAT replacement elbow to install. This also explains why the plumbing for the cooling system was not factory designed. There was just enough slope to the rotten elbow which enabled most of the water to drain away from the motor, but it sure does look fugly in there. The motor ran great before winterizing, and the turbo still spins freely. I was very lucky to pick up a parts motor with all of the correct plumbing parts, trans cooler, and a turbo with nice fluffy black soot on the blades. So there might be hope after all. Next month the bottom will be blasted by Billings Media Blasting to remove who knows how many layers of old school hard bottom paint. We'll see what that reveals. I don't live on Elm Street, but this is definitely a nightmare.

    Good luck with the project. Hopefully you bought it for a song.

    I'm good friends with Payless Workmore. He got me a great deal, relatively speaking. :D We'll get this ol' girl up to par.

    A few more pics.......and a few before pics of the boat as it basically sits now. Focusing on mechanical items first. Cosmetics come last. I was not going to float it this year, but I got extremely lucky and my name was called for a town mooring. So believe it or not, this will be in the water at some point this season.

    You definitely did yourself a favor getting rid of those fuse panels. Pretty gnarly stuff on the engine too. You'd be surprised how much needs to be fixed on some new boats as well.

    I'm on the fence about refurbishing that crusty panel or making a new one. It's a classic CAT panel I believe......with the perfect patina for a working boat :D. I was going to strip it and have it re-chromed and install new black trim, but am thinking of just fabricating a new aluminum dash panel instead because I'm adding additional gauges. I will be happy to donate it (minus gauges) to somebody's project if I decide not to use it.

    I like it more and more every time I look at it. Wish I had a use for it.

    Good luck with the boat...there is nothing like the smoothness of a 3208 Cat

    Thanks Mike. The motor ran extremely well the last time we had it running, so I was somewhat surprised to see the inside of that turbo. I'm hoping it can only run better once I get things straightened out.......providing ol' Murphy doesn't show up again.

    I'd take that panel minus the gauges if you decide not to use it.

    I managed to remove the turbo today. I'm going to check out the turbo on the parts motor and see if it's worth while to use it, but will most likely rebuild the original one, or perhaps combine the best parts with new wear items. No sense in putting junk back on. I'm surprised how simple this design really is. Will post pics of the rebuild process when I get into it. I'm planning to add exhaust gas temp and boost gauges to the new dash layout.

    Had the bottom paint blasted off today by Billings Media Blasting out of Glastonbury CT. A very professional father and son outfit that I highly recommend. There is absolutely no mess afterwards! This is the second boat that I have had them do for me. Give Kent or Glen a call at 860-659-1104 if you are in the CT area and are thinking about having this done. They use walnut shell as the media of choice. It does not tear into the gel coat on the bottom, and it leaves a fine haze of bottom paint that sands off extremely fast as you prep for barrier coat. The bottom looks to be in very good shape with only minor pitting here and there. No blisters worth mentioning, and it is bone dry. The only surprise to me was exposing the fairing blocks that someone added to the keel, right in front of the prop. Under all that old bottom paint, I thought they were part of the keel. At this point I'm not sure if this was done by the folks at B&S or the previous owner. Any Bruno owners care to comment on this? I fully understand the concept, but they are very close to the prop and I am thinking they may actually be doing more harm than good for that reason.

    That looks like a fun job..........

    I think it is Brooksie who added the fairing blocks and reported improvements? If I recall they were less streamlined/closer than that to the wheel too.
