Timi,
Propped correctly, 100-150rpm over rated fully loaded, and with a clean airfilter and aftercooler you won't see any smoke.
Even with my old jigga, set up as above, only hints at a whisper of smoke. Any direct injection diesel should not be black smoking underway. A bit of a puff if you are heavy on the throttle, and the turbo hasn't had a chance to spin up is normal, but it certainly should never be blowin black smoke in the cruise.
I thought that there were plans afoot to use the V8 Toyota motor.
Interestingly, have a look at the HP and torque the 6LP equivalent in a Landcruiser produces. The marine ones are seriously pumped up by comparison and that is why the propping and air and cooling system maintenance is vital.
Demand raw water and exhaust temp alarms be fitted during the engine fit. They are cheap insurance. If you overheat one of these donks through lack of raw water flow, they are anchors.
I have a "tell tale" plumbed into the raw water to the exhaust, that way I know the water has made it all the way through the coolers and out to the exhaust. Cost me next to nothing, but has saved me once so far. It is great peace of mind to look over your shoulder and see the water shooting 3 feet out the side underway.
Cheers,
Myles
I read about having a "water gallery" in the hull for the engine to draw water from - no scoop to get blocked up. Anyone know much about these?Originally Posted by Midnight
Myles, the tell tale's a great idea. It should be remotely aimable, too, so it can be used to wake up a sleepy deckie!
Cheers,
Tim
Carbon Really Ain't Pollution.
Good idea Timi, I didn't think of that. But I have managed to squirt a few unsuspecting folks in their tenders or at the wharf
Sea chests used to be the old term from that style of water intake. They work very well. All you need is a box an inch deep and say 12" By 8" built into the hull with a screen flush with the bottom. If you can have the screen made removable, even better.
For the tell tale, I just made a 316 stainless T, 1" to match the raw water hose from the outlet of the last cooler to the exhaust elbow, and I have a 3/8th inch nipple welded into it that runs out to a small skin fitting.
One day sitting in Days Gutter I further modified it with an old rubber bung with a 1/8th hole drilled through it pushed into the skin fitting so that it squirts a bit further out, making it visible at idle from the helm, even when sitting down. With the 3/8th hose to the 1/2 inch skin fitting it didn't shoot out far enough at idle and I had to walk down the back to check it.
1/4" hose and fittings would probably be spot on.
Have fun with it all mate.
Cheers,
Myles
