I was planning to do a haul-out in the next couple of weeks. One of the items on my list is getting my starboard prop looked at and repaired. It has a small chunk missing from one of the flukes and probably also needs to be retuned. Does anybody have any recommendations for a good prop shop...

So for my winter project we decided to finally get around to replacing the floor in the salon. The old floor was sagging a little in some places and generally had a little more flex than it should. The substructure viewed from the engine room is a hodgepodge of supplemental support, poorly...

Alright, this is probably a googan question but just try to humor me for a second...a common practice when we are out on overnight trips is to cut the engines and drift for a few hours to try to let the majority of the crew get some rest. Invariably though, it seems that without propulsion, the...

I have been considering installing a dedicated battery bank for my flybridge electronics and was exploring the possibility of going with one or more marine lithium batteries. Ideally, I was considering constructing a compartment on the flybridge to house them. My main concern (other than them...

Short Version: I'm wondering how it might be possible that I wound up with engine oil in my diesel fuel. (Detroit 8V71TI Engines) Long Version: A couple of weeks ago we decided to head out for a day trip of fishing. The 46C has three tanks, the two mains under the cockpit that hold 200...

I'm in the process of refurbishing a Yankee Boat Works dinghy that I was pretty much gifted. I took the rub railing / border trim off in order to paint the hull. Since the trim was in pretty bad shape, I committed to replacing it (ie: I threw it away). This is a profile section of the old...

I was wondering if these are the original design for the three forward hatch/skylight covers (1976 46C)? It looks like they were layed up as a single panel/piece of fiberglass with the center area just not painted in order to allow light through. As you can see, they are in pretty bad shape or...

Had a trip planned this past Friday to head out to try some night time sword fishing. Cleared the channel to the marina and went to set my initial heading into the autopilot when I realized that it wouldn't power on. On closer inspection, I noticed that there were droplets of water inside...

I have been researching some off-the-shelf, or more appropriately, off-the-Amazon options for installing a couple of cameras to monitor the engine room and other areas while underway. I would rather not have to run another set of wires all the way to the flybridge, so I was exploring wireless...

So last week I was checking the anodes on the raw water pumps. When I removed the brass plug on the starboard engine pump the anode, or what was left of it, came untreaded and was stuck in the opening. While I was trying to get a grip on it with some needle nose pliers to remove it, it wound...

Not sure if this is a question that could be answered here but... I just ordered a rebuild kit for my freshwater pump (8V71TI engine). When comparing the parts in the kit with the ones extracted from the pump I found that the impeller in the new kit does not have a ceramic insert on the...

I have come to the conclusion that there must be a crap-load of diesel boats in advanced states of disrepair around the Pensacola/ Mobile/ Fort Walton Beach area, since apparently there is no one within 100 miles of here that works on them. I guess I can understand, since Series 71 Detroit...

Well, thought I would modernize the 12V DC lighting system in the engine room with LEDs. I used a couple of sets of the low-profile, fully encapsulated, accent type lights in bright white. I placed them at strategic locations such as facing the fuse panel, battery switches, gage panel, Racor...

I'm not sure if there was originally a check valve or something installed to prevent this, but whenever I top off my tanks, no matter how careful I try to be, I always wind up with about 2 tablespoons worth of fuel belching from my vents. Needless to say, by the third tank it is obvious to...

First off I know the old 2-strokes are loud and I have no problem with that. However, one thing I struggle with is when I'm running at about 1300 rpm or above the sound from the exhaust is similar to the sensation you get when you roll down just one window in your car X10. I was wondering if...

I have an Onan MDJF 15Kw genset and was wanting to see if anyone knew what the normal operating oil pressure should be? At 1800 rpms with no load it is showing just under 40 psi on the gauge. According to my manual it says it should be greater than 25 psi but doesn't say what the top range...

Below is an exhaust mixer elbows off of my starboard engine that I removed several months ago while working on one of my turbos. Obviously it has seen better days. I suspect the others are in about the same condition. At the time, I looked around for a set of replacements and was finally...

My port engine was running hot the last time I took the boat out a couple of weeks ago. To the point where the high temp alarm sounded. Since I had replaced the raw water impellers a couple of months ago I suspected it was something with the freshwater side. I pulled the thermostats to check...

It appears that I am going to need to rebuild one of my turbos and I'm trying to make sure that I order the right kit. It's an AiResearch M24 turbo. The plate on the backside of the compressor housing lists the Model# as TH08A64, the P/N as R5143110, and the S/N as B2186G B0604. I have not...

I was wondering if there was any reason that Pex piping should not be used for replacing the water lines on a boat. My 46C originally had copper water lines but over the years as those failed the previous owner(s) had patched them by splicing in sections of flexible water line. Last evening one...
