On another forum - re stereo speakers, nothing to do with boats - there was a discussion re tinned electrical wire for speaker crossover units and question of where to get it. I mentioned that I used a lot of "marine" tinned wire on our 53 ft Hatteras so it was available at any marine store. A...

While working on the forward bilge pump, I noticed that one of the thru-hull valves has been off since I purchased the boat- never noticed that one forward. In tracing the hose, it goes to the galley maid head pump. There are two raw water hoeses going to my pump- one at the end of the pump (which...

I am looking at a boat that has been very well cared for but has about 1900 hrs on 857 hp 12 V 71s. I am wondering how long do they usually last before rebuild? T.G.

I have the smallest DD engines ever used by Hatteras, 453N's rated at a full 112 HP, in a 48 LRC. But, they are true to their breed and do leak. However, unlike the other small drips and weeps, now I have a leak developing that got my attention. On the port engine, at the rear inboard corner, where...

Question re: The Interlux hull paints, one a one part "Brightside", the other a two part, "Perfection". I have used their 3 part varnish and it wears like iron, but nasty stuff vapor wise. Is it worth using the 2 part paint? If it wears like the varnish, I would think it very durable. Any...
