Hei outta box 75$

if your using delco external hei voyager set up something is way wrong we run a hard core 540 big carb it starts with no kick back and in the heat turned 6500 with out missing a single plug firing it runs and starts better than the msd with start retard this boat even idles and stays crisp on throttle up timing is at 34 at 4000 idles around 18-20

Drunk. Yes.

What really ticks me off is that my timing light took a dump right in the middle of trying to figure out what the f was going on.

Still drunk.

First time in the water with the new engines. Wasn’t just the engines. I blew a hydraulic line too so no steering. Oh, and I think my gf is out the door too. What a day.

Back to drinking.

So with Voyager… ever seen the timing hang? I set to 34 degrees at 3500 but it remained at idle. This was all during troubleshooting (I thought timing was already set but wasn’t’). Just odd running. This was port. Starboard was finicky going into gear but since the timing light quit, I had nothing to tell me if similar was happening (don’t think it was on that side).

Dying in gear from 1k rpm idle an issue. Like 500 rpm drop, enough to shut down with no recovery.

who's custom cam?

They are my cams that idled at 700 all day on my carb setups. I swapped them out when I went EFI. I believe timing was 28°-36°

You can fix broken boats. You can’t fix broken women.

Let’s get started on the boat and stay away from The booze. It’s obviously isn’t helping your attitude. :wink

Timing light first.

if your checking timing at 1k, that probably explains why you think timing is hanging, as the advance comes in by big amts by 800 rpm.

This is from volvo penta manual on their engines using the GM EST eith carbs.

Morning folks.

Timing… I was trying to set total timing to 34-35 at 3k figuring that it would be at the top of the curve. Bringing speed back down to about 1k the timing was still holding at 35. That’s when I thought there may have been an issue with the distributor. Checking the same on the other one was more along what I expected and inline with the Volvo specs. I went back to the problem one and after shutting down, it seemed to correct itself though I did not check timing at 3k again (just idle). A few minutes later the bulb died in the light and we were done.

Electrical connections are all good. Clean grounds, good cables.

Timing was one issue. Dying in gear was an even bigger one. According to the rpm on the timing light, we were going from 960 to under 600 and then stall. They would restart without a problem but stall quickly going into gear. Made getting back on the trailer fun. AFRs were showing a little rich, mid 12s at the high idle. Thinking something is up with the carburetors. I didn’t have a chance to hook up my vacuum gauge during all of this.. wish I had.

I’ll mess with it some today. Also need to figure out which hydraulic line is spraying all over the transom.
