I have to say I love this boat though. Power is good and it handles really nice. Turns sharp. Will be a really fun boat once the motor is dialed in!

Yes its really odd. Had a few backfires tonight too which I had heard before. Also at one point while running the throttle up it would bog and the rpms would not increase, then a short time later, it would quit or nearly quit on occasion.
Wex, sounds like you tried everything too. That HEI you installed, I don't imagine its marine and not sure it matters?
So they have no coils and extra garbage huh?
Earlier I thought to myself that if we don't find anything tonight, its going into a Marine shop but at a couple hundred an hour and have them go through the same routine, replacing the whole distributor might be the way to go. Pretty disgusted right now.

On the upside, I got a ride in Jason's sweet CV! Unfortunately, my use of the video on my phone leaves a lot to be desired. So much so that I didn't get any.

BTW I do have an HEI, vintage, I don't know, nor what the condition of it is or how to wire it in. Came with the 350 I have in the boat.

So that is the issue at 45 seconds into the video ?
hard to say not being there but it sure seems like a fuel issue.
i have put in a temporary fuel pr gauge for testing.

It actually started a few seconds before that when I could tell there was a loss of power and that another dying session was about to start, although this time it didn't actually quit. Earlier we were just idling and it died.

Your problem sounds like what my V195 was doing. I would run fine but then it was like you just shut it off. It would start right back up no problem though. That is my next project. And a noise in the gimbal area on that one too I love boats! I love boats! I love boats!

Rosscoe,
The HEI setups are self contained, coil is built into the cap. Some may argue this, and experience varies, but they are advertised to have alot more spark throughout the rpm range, and don't fall off at higher rpms, in any application that applies to us anyway. This has been my experience every time in straight swaps changing nothing but distributor. Always a very noticeable difference just in all around running. You may have to adjust idle and idle mixture to adjust for the better burn. Again, I can't guarantee this is your fix, but man does it sound familiar! You could put a clear fuel filter at the carb, run it till your issue arises, immediately shut it down and check the filter. If there's fuel, can't imagine how it would be a fuel issue. And no, it's not a marine setup, but you could seal the vent better or tap in a vent hose to route elsewhere, but all the performance boat sites literally have hundreds of guys running street setups without issue. Doran I believe is running something very similar with great success.

I have a non marine HEI on my 18

My current relic is vented anyways. It has a small screen on the base.
Man I am just not sure which way to go. Sometimes it seems like a fuel issue and other electrical!
If the electronic module is at fault, even being new, I have no idea as to how to check it if its breaking down or whats going on.
130.00 is cheaper than taking to a Marine mechanic.

Anything special info they are going to require to get me one that will work or "just give me one that fits a dang 350!"

I have the MSD Streetfire on my CVZ as well.

Rosscoe · « **Reply #51 on:** July 11, 2013, 12:12:06 PM »

Argh MORE new plug wires!
I wonder if I can take back my new accel wires.

Easy to wire D?

I have plug wires you can have. They just are not pretty like Doran's!

Rosscoe · « **Reply #53 on:** July 11, 2013, 12:20:26 PM »

Looking at the Streetfire on MSD's web site and it shows a rotor, so these still have parts that need to be replaced as opposed to the optical setup I have now? I guess technically mine does have a rotor.

thedeuceman · « **Reply #54 on:** July 11, 2013, 12:28:52 PM »

sounds like i wont cost anything to test with an hei from Jason, just do that and prove that it is, or is not Ignition.
when are you going to test next ?
maybe we could have a mini-meet

Rosscoe · « **Reply #55 on:** July 11, 2013, 12:54:04 PM »

I have an HEI but not sure of the condition. I think Jasons might be Ford style?
I'd have to get it installed (correctly) and wired. I've only pulled a dist. once before.

Here is what I have.

thedeuceman · « **Reply #56 on:** July 11, 2013, 01:03:26 PM »

piece of cake, make sure rotor is pointing same as it was on the old one, 1 wire (hot from ig sw)
you will need to put different wires on, if you have the set that came off the motor, or a set from Jason, i may have a set here.

Rosscoe · « **Reply #57 on:** July 11, 2013, 01:15:56 PM »

I'm thinking this would be the easiest and cheapest thing to do first. If its the distributor, then I think I would replace this one with an MSD.
Maybe I can clean up the innards a little.

http://www.ebay.com/itm/370774786067?item=370774786067&viewitem=&vxp=mtr

Looking at this one on Ebay too. On one hand they make it sound 100% complete, then in the install instructions it says

on GM HEI distributors, it will also be necessary to transfer the coil and coil cover from the old cap to the new one).
I've tried calling several times and no answer.

thedeuceman · « **Reply #58 on:** July 11, 2013, 01:39:00 PM »

That almost seems like "too good of a price" for a complete unit.
also, it would be fine for testing, but i think marine engines typically use only mechanical advance
may be ok to just leave the vac disconnected ??

Rosscoe · « **Reply #59 on:** July 11, 2013, 01:43:41 PM »

Yeah I dont know about that stuff. My HEI has a vacuum thingy sticking out too. Maybe it can be plugged?
