SPARES is another interesting topic. I worked on a lot of Fast Attack Subs back in the 70s and 80s. These guys go out for 3-6 months without support. Room for spares is at a premium. They actually fill up the companionways with food and eat their way down to the deck. So, a lot of thought goes...

I can't cite all the statistical analysis anymore but I can give a counterintuitive example of a similar situation. During WWII, a Corsair fighter squadron in the So Pacific wanted to improve their combat readiness. I can't remember the real numbers so I will just use numbers for illustration...

Just an observation, typically, 2 engines will run 4 times the cost to operate, not double over a single. Not saying this is bad, but it seems to be more realistic from an analytical standpoint. There are all kinds of statistical studies, reasons, etc, but this just seems to be the real world...

This is a fun exercise. Mission, location, type of boating all will determine what is best for you. Have had 2 big twins, 3 singles. One 70fter when lost 1350hp engine the thrust was so bad I could not manuver in close quarters with asymetric thrust of other engine. Had to call Sea Tow to tow us...

I really like this idea, simple and easy. I would just improve a bit. There are now so many cheap CCTV systems out, I would mount a camera viewing each glass. So, you can go on a run, record each station, including your tach/speed/instruments and record the whole thing to sit, playback and...

My boat is a 350, There's enough room (just barely) to get the sender out on Stbd tank. The placement of the Port sender on my boat is such it cannot come out but further forward there is room and I had a spare hole and cover in the tank that I used. So in the port tank I have the new and old...

West Marine has a generic sender that I used to replace the port sender. Very easy, can't remember the price but under $50 sounds right. Not worth trying to repair unit if it's bad. Only issue I had with port sender is it is under the step and impossible to remove (no head room). But there was a...

Unfortunately, there are so many players that can be the culprit here. My neighbor hit a rock in SF Bay 3 years ago. Boat went in for repair. When it came out, yup a vibration. The boat has been in and out of the shop most of the time since, looking at all the items cited here. Hope you find the...

I know this started with the stern thruster for the 34, but I am interested in anyone with a good stern thruster installation on the MS350/390. Another FYI, most thrusters are controlled by two relays to change polarity on the motor. One side died on my bow thruster when anchored out. Thruster...

Who knows why builders label their boats something. My MS350 became the MS390 and both, identical, are more than 39ft. Small rudder, rudder placement, windage etc makes the "burst of power" method of turning just not practical in close quarter docking. I have watched Mexican shrimp boat captains...

These look identical to mine in my MS350. I have taken them apart and a small plastic tab is broken that usually allows a metal plate to click and hold the Ports open. I have 3 broken of 4 ports. I be interested in who made them and see if we can get parts. Probably a wishful exercise since...

Your tech is correct. Under instruments on fly bridge is perfect. Sac Delta is the Sacramento Delta located in Calif where the Sacramento River from the north meets the San Joaquin River from the south before they flow to San Francisco and out to Pac Ocean. There are literally a 1000 miles of...

I bought a used Raymarine system for about $500 to replace the bad computer unit in my Raymarine system. It came with the fluxgate, rudder position and an extra head (think it's a st2000 but can't remember for sure). It works fine at low speeds ( MS350 only has low speeds LOL). Tracks incredibly...

There is another method I have used and that's a beam thru the windows and then a beam across the engine. My Willard set up fine for that configuration but that was only a Perkins 4-109 50 hp

Don't know what happened but I did reply that those are the hydraulic press frames I used. Don't have pictures. I used the frames as you suggest, with a beam to get hoist aligned with engine for balance. The frames go together easy, don't take up much room. I lifted (sp?) 2000 lbs with one...

Yes, that's the press. Easy to assemble and handle. In my application, I used them to raise a 1350hp MTU that weighed 4000lbs. But I only had to lift one end then blocked it so we could get the 600lb crank out. Had to drill a hole in the salon floor. Using a single press frame, it was about all...

What happens if you find the "Other" HIN and it is correct? Now you have a boat with two different HINs. I had similar issue with a truck that had incorrect VIN on registration for 20 years. I finally wanted to sell the truck and went to DMV and had to show the truck and they changed the...

Probably a little late now, but we bought a few hydraulic press rigs from Harbor Freight and used then with a beam across for our A frames. Cheap and afterwards I had a press for everybody who helped removed the engine!:banghead:

To Lshulan: Mounting pump on flybridge is fine. That is exactly how mine is located and works fine.

No question that what a radar shows bears little resemblance to what's out there especially on marshes, rivers with turns, tributaries, etc. Not saying I haven't used radar a lot, just now my operations are more fair weather ops. Old radar keeps working, only so many hours left in the magnetron...

By all means if you are talking trinkle charge it will work. But remember, winter will cut your solar output at least in half. I would not just plug and leave. If the batteries get down the trinkle might not return them to up. Think about taking a little Honda 2000 generator or something and...

Actually, I only really use the radar maybe 1 or 2 times a year when we go downbay to SF Bay. Don't boat in the winter as I am over in Hawaii boating with much smaller vessels. I need to turn on and use radar in bright sunlight a few times a month just to exercise it. So, adding new equipment is...

On another post I commented about drilling an access hole in the STBD flybridge seat to snake wires from flybridge to salon. I could get a wire pull thru the rigging tube but wires are so cris-crossed over there was no way to pull another cable in there. So I used the cable pull and went outside...

Imagine buying a $900,000 plane with Garmin electronics that is obsolete in 5 years, but the plane is only certified with that electronics so you can't change it. I use 1940s "steam gauges" and an Ipad for nav. At least with your boat you can upgrade your electronics without suddenly being...

The round light in the salon is controlled by a light switch located at the desk on my 350. I don't think the 390 has a desk, but I would suspect the switch is in the same location. My PO added a florescent light to that circuit located over the stove. There's a second switch there that controls...
