The biggest mistake most shade tree electricians make in running conduit is putting to many bends in each run. NEVER have more than a total of 360 deg. of bend per run. If you do, you won't be able to pull wire through it. The less bends the better.

Advice needed. I want to install a bow thruster on my 41ft, single engine. Now I'm only getting 6.5K @ 1800 and 7K max. at full speed (2000-2200). How much will a bow thruster hole reduce my already snail speed?:banghead:

Kicking around ideas on building my own propane locker. As long as it is to USCG specs I see no reason it wouldn't pass inspection. It will be used to supply my Magma grill on the aft deck. Everything else on the MV is electrical. Any thoughts/suggestions?

Well, I'm on the RM horse now and in the middle of the stream. So I'm hanging on for the ride. So far I've learned that RM help for the individual is none existant. If your a Corp., great; a private boat owner, "All of our reps are busy". I've been unable to even get a straight answer on...

I've seen several pics of LF120s with a chrome/SS valve cover. Anyone know where/who sells one?

Been waiting to install a new chartplotter for a year now. Couldn't decide between Garmin 740s or Ray Marine e7d. Finally threw in the towel today; orderer the e7d. Should have it Thursday. Suggestions?

Time to change my oil on the FL120. I'm planning on refilling with Mobil1 syn for diesels. Any advice?:blush:

I had a leak at the rear seal, had a shop replace the seal.* No leaks for a short time, then leak started again.* The orig. leak was*by the*seal and flang coupler shaft.**The new leak isn't*there; I had a hard time finding where it was comming from.* Finally found it was leaking at the inside of...

OK, I give up. I can't find the problem with my OP gauges.* Both guages peg high when powered up.* With power off they read about 40; (0-80 guages). When eng. is rev'd to 1600 rpms the needle will drop from pegged to about 80 and when lowered to idle back to pegged again. I guessed both guages...

My tranny makes a loud clunk when I go to reverse, only reverse.* When I go to foward, smooth and quite.* I'm sure it is a linkage adjustment problem.* Can anyone advise me on how to adjust it.* It's a Borge Warner Velvet Drive on a FL120. Thanks

Mine has a Jabsco flex impeller on the bottom for raw water heat exchanger and a belt driven/metal implr pump for the eng. coolant. I rodded out the heat exch. best I could; blew through the intake pipe an had a fair amt. of air flowing. I have been unable to find any restrictions anywhere on...

I changed the coolant when I bought the boat a few months ago. The gen has shutdown a couple times since; high temp. I check the coolant an each time the tank is half empty. When I refilled it this time I left the cap off an watched for flow in the tank; none. I'm just guessing there should...

On my Onan 7.5 MDJE, the fresh water coolant isn't flowing.* I checked the stat, it has already been remove by orig. owner.* Then, I remover/diss.*the water pump; everything looked O.K..* I blew thru the hoses to check for blockage; everything seems to be open.* What am I over looking.

John, my alarm was working with the orig. alt. The alarm would sound when the key is first turned on; a few seconds after starting it stopped (guessing that was the oil press. sw.). The only other time the alarm sounded was when my water temp. got to high. A bad impeller and stopped up HX caused...

OK, just left a LF site. Drawing there IDs the part as an 'oil pressure switch'. So, I'm guessing it is used to send an alarm to the buzzer if I have no oil pressure. Not sure how that works, the way it is wired (going thru the VR). But I'm hoping it is still safe to use the boat, as long as...

I put the Delco on yesterday. The tension bracket didn't fit. But, I hung everything on loose just long enough to check out my guages. The amp was showing a reading as well as the oil pressure guage. Tach of course was dead. Can anyone explain the function of the thing in the picture...

On my LF120 I was not getting any reading on my amp guages; tach works o.k..* So, I pulled the alt. (motorola/prestolite) off; found broken wire to one of the diodes.* A new direct replacement, 300.00.* Local shop has Delco that is suppose to bolt right up; 75.00.* It's a one wire hookup; no...

Just bought boat, it's been sitting for about four years.* It has a LF120; starts great.* Temp guage stays around 180 all the way up to around 1600 or so RPM.* If I try 1800-2000* the temp goes to 200+ quick.* Now, after reading the post about 3 vs. 4 blade props I'm thinking the prop may be the...

I'm located in Louisiana; refered to as the North Shore area; Madisonville.

Anyone know who makes Sunbrella tops for trawlers?* All the sights I've looked at have widths up to 103" only.* The one on my boat is 132" wide by 8'6" long*(approx.).* HHHHEEELLLPPPP!

Just bought a '79 41ft. single eng. with all orig. eq.* My question is, how can I upgrade the eng. data (all gauges are elect.) to a NMEA2000 system?* I'm wanting to install a Garmin5212 (main deck) & Garmin720 (fly).* Garmin support has been no help.* My eng. is a Lehman Ford 120.* There has to...
