Maybe I've outsmarted myself again. Lol
i have a shutdown circuit on my oiling system.
It shuts the engine off in the event that I break or throw a dry sump pump belt.

Maybe be I should rework it to display a bright LED like Dan showed and then time out and kill the engine after so many seconds.

I used to have 18 psi oil pressure after running hard (warning lights on) and currently my water pressure warning lights are on during idle. If I had those wired to shut the engines off they`d never run lol


For me it`s more or less for being able to relax a little more while running, not having to watch all the gauges constantly. When I threw a water pump belt light came on , I slowed down right away and the headers were already crackling HOT. Without it who knows how long I would have kept going before noticing/overheating the motors, headers etc..

All the warning lights are wired into a weatherpack connector, makes it easy when pulling engines.

My oil PSI cutoff switch changes states at 12PSI.
after a hard run I have 210 degree oil temp and 30PSI of pressure.

Thats kinda what saved me one time. I blew a hose off the outlet of the sea pump. Was running along, and noticed my factory light for the bilge pump come on, on the dash. I was like wtf, looked down at the gauges, saw starboard temp gauge at 210, and shut it down. Opened hatch, and found a ton of water. Without that light, I probably would have smoked that engine, and the headers. back then I didnt have a temp alarm. Point is, the light caught my attention very quickly.

I saw your boat in some writeup on facebook I think. Gotta say, you did an AWESOME job on it. I know it took a decade or so, but it was worth it.

Hows it running?

thanks for the compliment MT.

almost 6 years to the day I dragged it home. Lots of hours in the barn!

Boat runs like like it's on rails. So far, I've pushed it to the mid 70's. I'm trying to take
it slow as I'm still sorting all the systems out and learning how to pilot it safely.

we put 90 miles of trouble free operation on it last Saturday. It seems fairly capable for a 24' boat.

I don't use Facebook, but I've heard the boat story has been passed around on that site.

If I were to run the larger psi baker pump any suggestions on fuel regulator. I'd like to get away with one per engine to plumb to a fuel distribution block so having little restriction is of importance (10 AN in/out). From what I could find magna fuel and edelbrock had the best gph I could find (180) that well exceeds fuel consumption at wot.

Otherwise skip the fuel distribution and use a 4 port outlet fuel pressure regulator. Wish I could get way with the 7-9 psi pump as there rated for 1,200 hp or 130 gph. Might be so - just not long runs. I cdedppl proved that... I like simplicity less plumbing the better.

Icdedppl, Do you still have dyno sheets.

I would like to revisit this discussion. Fuel pressure gauges just live a few minutes because the needle is swinging wildly from around 4psi-10psi with every pulse of the pump.

Using Holley 12-845 regulator, installed just like diagram 2A in the install guide. -10 to the pump, -8 to regulator and carbs, -8 return. Holley tech support is of no help.
