Hope you have better luck than we did with Pettit Vivid paint. We used it to mix white with a little black to get the bottom a nice grey color. Looked great, but did not last long here in the Caribbean. Running gear was without paint in about a year. We actually spoke to a Pettit rep at the Miami Boat Show in 2019 and he explained that they did not recommend their Vivid paint for use in Puerto Rico.

Great job!

Very interested in hearing about your instant hot water heater. You happen to have any pics of it? Or know what model/size it is? I'm definitely leaning that way but it's all a tradeoff. The instant units pull a load of amps and I'd have to run new wire and new breakers. Not a deal killer but definitely a bit of a pita.

I haven't taken the cover off and taken a good look, yet. It's small. So, I hope it works well. The water tank water is so warm already, it doesn't have to do much.

Just reached around the SB 892 and snapped these tonight. The direct heater looks tiny next to the ol Charles cooker.

And yes, I'm sure that yellow wire is the crap you use in a house and has no place on a boat. <facepalm> I hope that's the last of it.

Sorry, don't know why this pic is upside down.

Just found that water heater online. It's a 110v crapster from WalMart...for residential use. I'm not surprised.

See what I'm up against?!

I'll take pics to show when I change it to a proper marine model and rewire it all.

did you prime the running gear or straight bottom paint to it?

There are some square or rectangular water heaters available from Isotemp- also cylindrical ones that might fit better, too. Hooking up the coolant loop from one of the engines gives you 180 degree HOT water, which you don't need much of, so it goes further. I have a Seaward water heater in Blue Note that is at least twenty years old. It is square.

Getting a water heater with a coolant loop is very attractive to me. After reading up on the instant hot water heaters I think I'm going to take a pass on them. Sounds like they can be hell on dock power with tripping breakers...etc. I've got a couple feelers out to my suppliers to see what marine units are available.

One question on the coolant loop, where would you pull the coolant from and where would you return it? Any preferred places to get it from and return it?

If using a coolant loop do not leave the valve 100% open. It will overheat the hot water and can burst an old non copper line if you have any. This happened on my older 34. On that boat the valve is just barley cracked open and makes great hot water. Start at maybe 25% and adjust from there.

The Isotemp comes with a mixing valve to temper the hot water from the coolant loop.

Here's a snap shot of heater loop plumbing for a 671.

Apparently they used the same epoxy primer from the hull on the running gear. Paint on the hull did not hold up too well either, we were getting growth build-up much sooner than expected.

Thinking outside the bucket here. Anyone ever loop it to the gen set? In theory, the generator will make hot water faster using very little fuel-less noise and less smoke as well. But again, I've never heard of it, and maybe there's a good reason for that.

Other than location that would be a fantastic idea. I'd have to run 20' of coolant hose just to get over to the water heater.

 

[jim rosenthal]

You COULD loop it to the genset; it would just take longer, because the genset diesel is smaller and doesn't produce as much waste heat. But it would work.

When we hooked up the water heater to my Cummins diesels, I think we asked the Cummins dealer where to position the in and out lines. They both have shutoffs on them. It works great; the only problem is that the hot water is HOT and stays HOT for a day or two after shutdown, especially in the summer when the engine rooms doesn't cool off as fast, so you have to caution people not to use much hot water. If you love very hot showers, and I do, it's great.

Timed the injectors Sat and seatrial on Sun. Maybe it's in my head but after timing the engines sound a little 'meaner' lol.

Fuel, water, baitwells, tuna tubes...etc all full. Idling out to give her a run.

25knts WOT, hit our goal rpm of 2350! woot woot.

 

[rustybucket]

Ran her for about 50 miles total. Cruising at 19-20knts at 1950rpm. 1900 feels like a good economical cruise, so I'm thinking we will spend most of our time there.

She felt quite a bit more torquey than before. Engines sounded very strong and throttles were quite a bit more responsive than before.

My current blowers do not have the ports for the blower bypass mod, but that project is definitely on my list for a winter project this year. I think if we can unload the engines just a little they will live a long and happy life.

After we got back to the dock sunday started working on a countertop for the L shaped tackle center I had professionally built (twice) for the Salon. This goes where the old L bench seat and table was.

This is just the solid surface cut, there will be plywood backer and an 'edge' put on it.

We also spent a considerable amount of time fixing every visible oil leak/slobber on the engines (about 16 spots total were addressed). We re-sealed bolts, changed copper washers, added copper washers where somebody had used a lock washer instead....etc. We also found one turbo was leaking a little exhaust/soot, so we pulled it, cleaned and re-sealed it. Seems like things are starting to get buttoned up and this ol gal is close to seeing some blue water!!

 

[JuiceClark]

That's great stuff. Love those transom wells, the bridge hardtop...nice ride.

I wish I knew a guy down here to make custom cabinetry for the boat.

 

[racclarkson@gmail.com]

Yep, really good looking rig. That's a bunch of leak tweaks. It'll make the world of difference going forward.

I did the same project last year. Ended up dropping my struts to have them bored out to a standard size (during the repower, somebody bored them to a wierd size and turned down the OD on the cutlass bearings). They trued the couplings and when I got the final bill, I was a bit suprirsed ($1700 or so I think), but it sounds in line with what you paid.

It was worth it in the end. Smooth and I know it was done correctly. I put all new bronze bolts in and sealed with polysuflide Lifecalk.

https://live.staticflickr.com/65535/51125682334_6e5d4a0276_c.jpg Is this the “Smartrail” lifting rail on the chine? I’m installing a pair of these now. Did you own the boat before these lifting rails were installed and I’m wondering the performance difference between before and after. Your comments of hiring contractors and the ensuing shitshow rings as true as anything could. Doing the projects yourself, you know the details are attended to. Only things I won’t attempt myself is cylinder liners and upholstery. Keep up the good work!

We did install them, I did not ride in the boat prior to installing them. Everything I read about them was positive and i have been happy with them.

I have enjoyed reading your posts,especially on the engines . Some people seem to think that the 8V92 engine is a hand grenade with the pin already pulled , sounds like you are getting good performance
