Our 43DC has eight six volt batteries in a painted plywood box between our transmissions from a previous owner. Our surveyor said it needs to be water tight. I'm not finding a 8 battery marine battery box. 4 twin 6v boxes are doable, but kinda bulky. Can anyone share their thoughts on a proper...

We've been getting our fuel from a local ValvTeck dealer, but after seeing their additive was less than impressive in the Spicer Test, I'm interested in supplementing for lubricity. I'm not interested in loosening up 38 years worth of crud laying harmlessly on the bottom of our tanks, if that's...

Recently developed a slow drip while running at the 1" pipe elbow pictured. Tried 3/4" wide teflon tape (leaving first thread uncovered) only to have it leak after a couple hours run time. Next was Permatex "high performance" thread sealant ($15) and the "recommended for best performance"...

Can anyone tell me the correct method of assembling these fittings? I'm ordering new hose and haven't seen anything on how it should be done. I have had one apart and back together OK but would like to see a procedure if possible, considering the consequences of a failure. Thanks for any input.

Can't say I wouldn't at least try it out. eFoil ($2500)... https://m.youtube.com/watch?v=1yEmtz4ZVMM

Searched 12 pages of archives nothing found. Anyone know about replacing these hoses? I believe the fittings are reusable? Is the hose (still) available? Thanks for any help.

Might be fun to gather the outfits at Goodwill or Salvation Army and reenact this Hatteras ad... https://m.youtube.com/watch?v=3JO4kyUsnRM

This 8v71 project near us started as a tuneup to possibly correct excess smoke. Mechanic A ran the racks and adjusted valves but was unsuccessful with the smoke. Mechanic B was called in and has dug deeper. Owner and mechanics are in discussions.

Would like to have more than the modest entry in our drawings, anyone have a manual or schematic to share?

Planning our first fuel filter change. Would like to know if the cartridge type filters (primary & secondary) can be serviced from the center hatch, or do all three hatches come out? If it's a matter of purchasing spin-on adapters and filters to get around having to open all three hatches, (in...

I have the "large" Jabsco impeller puller from West Marine (286880) that worked OK on our J&T 6-71s but won't grasp the huge impellers in a friends 8-71s. I'm not finding any pullers at Jabscoshop.com but I've missed things online before. Anyone care to share their successes in pulling really...

The recommended SAE-API Class CC oil is long obsolete. Delo 100 offers CF-2 and Delo 400 SJ levels of performance and protection. The newer oils have seemingly attractive verbiage such as "enhanced protection against oil oxidation, viscosity loss due to shear, oil aeration and engine wear"...

Wifey has a habit of shifting from forward to reverse or vice versa in a single motion, and I am sometimes challenged to remain calm when that happens. Looking in the Twin Disc Manual it appears to be perfectly OK at idle speeds. Am I reading that right?

Thanks all for the great advice here. Even though we weren't having any cooling problems the archives here got me going on impeller change outs, having been running on luck since March. Took a look in the trans cooler as advised and it's clear now. Surprised how hard working this pump is, seeing...

Looking for a replacement, or a shop that could restore the plating and letting on our control. Thanks, Craig

Can anyone fill in the blanks on our Alarm Panel? Seems to have been over-cleaned at one time. I know a guy who could replicate it.Thanks for any help

I'd like to tidy up our raw water lines but need a short near-right angle hose that I'm assuming was once in the spot circled. Thanks for any thoughts, Craig

Changed out a toilet on our '78 DC and the new one exceeds the capacity of our 30A D51 by 10 amps. I'll call Sam's Monday but welcome the wisdom found here in the mean time. Thanks, Craig

Specifically, can a pair of 8-71 TIs in a 53' with 1.5 to 1 gears cruising at 11 knots at 1300 rpm get better fuel economy than a 43' with 6-71Ns turning 2 to 1 gears at 1900 rpm at the same speed? The bigger boat has four more injectors, but they're firing 600 fewer times per minute, seems...

Anyone here equalize batteries? For the last four years I've been working at a light-rail system with over 300 12v lead acid batteries providing backup power to rail switches and crossing gates and even the old timers there say they've never seen it done, which means nothing considering how the...
