    Default functional gauges?

    So I'm going to replace my gauges any i'm trying to decide what the best options are...

    Currently I have... Oil Press, Water Temp, Speedo, Tach, Voltage, and Fuel


    I'm thinking about swapping out my Voltage with a water press? am i crazy? I just dont know if I feel like thats a necessary one...

    No way would I do without a way to see if charging system is operational..IMO..oil, water temp. volts, tach...is all necessary to me..speedo who cares...fuel gauge in certain situations is ok..but I don't have one...

    So I must have a tach, oil press and water temp. From there I want oil temp and then volts or ammeter. If I have room then I will do fuel level. If turbo then fuel press and manifold press (especially after loosing fuel pressure once in a turbo motor while under boost).

    I suppose, I've always kinda felt like charging system issues are one of those things that never get caught until it wont start, then you start troubleshooting parts. I'm just kind of throwing ideas around I guess.


    RCL: So can you gather any more from the gauge than.... +13 - 14.5v alt is working, and anything else you prob got an issue ?

    When I got my Cole, the dash had been drilled for 4- 2 5/8" gauges, plus a tach and likely a push button for a starter. I filled all the holes and after the build the only guage in the boat is an oil pressure on the motor. Water discharges next to the driver so I can see the flow. Run a mag, so no alternator, just a good battery I charge up every couple outings. A 2' long wooden dowel is my fuel guage. Cole TR-4 with a 557" BBC, simple is good....

    Thats part of my reason for wanting the water pressure gauge, I dont have any water dump,the only exit for water is the exhaust. If I had a dump on the side i'd be content with that. I'm currently rocking the wooden dowel dip stick too, while it does work its not ideal i guess for a lake boat.

    In the early days when we ran cooled logs with OTs, we ran all the water out the pipes, no problem. Same with snails but you couldn't see the water dumping out the boat. However, if you're running headers, you cannot get enough water through the headers to cool the motor. In the Cole, I run a seperate -6 static pick up on the plate that splits between the headers and the v-drive. I use an 0.080" orifice into each header to limit the amount of water that goes through them. The rest runs through the v-drive. At idle, no water runs through the headers and very little through the box. As soon as you're on plane, it's wisping out the headers and cooling the box nicely.
    A MagnaFlow 1" pump can generate up to about 25lbs pressure with a -10 pick up and discharge. On my Super Stock Bezer, it was enough to push past a FelPro performance head gasket or head studs in a BBC block. I added another -10 discharge line so I had 2, that fixed it. The Cole has better parts and a single -10 in and out works fine.
    Just as an FYI, a single -10 pick up force fed without a pump can generate up to 75 lbs pressure at 130 MPH. I didn't test it but have confidence in the guy that did. Was tested on a K boat with a data aquisition system on it.
    Best of luck....

    I've always (50 years+) run a "TellTail" discharge line out the side of the hull within sight/feel of the drivers seat. I use a #6 or #8 line into the thru-hull fitting from the top of the engine water cooling system. I tap the thru-hull fitting inside the outlet to pipe thread and use a drilled ( 3/16" or 1/4" hole ) allen type brass pipe plug to adjust the output of water. No water pressure guage needed to check water flow at idle, or running and a quick feel of the discharge water monitors engine tempature. It still allows ample discharge water flow for the exhaust system.
