Carver 3607: port engine stumbling/missing

You saw that I listed the advance rebuild kit in the paragraph under the parts lists, right? This particular store can't get it, but he provided me with the part number to find it elsewhere.
I'm pretty sure that would provide the parts to correct any issues with the advance.

However, I am leaning towards just doing the full Delco Voyager EST conversion kit, rather than spending $ on refreshing the old distributor internals.

Can anyone that has done the full conversion in their Carver with Crusader model 350 carburated 454s confirm that the RH rotation engine requires a different kit?
I talked to George at marineenginedepot.com and he says "I have to get shafts machined and we send those out along with bearings". He expects a $40-$50 additional charge for this. However, he doesn't know when they can have a RH rotation distributor kit ready for me.
While I'm not in a huge hurry on the right engine, I don't want to wait indefinitely either.
 
I've thought more about this, it could also be the bearing in the distributor. I hope all the parts fix it. If do put the new points in you have to get the dwell right and check the timing. Good Luck.
 
Next time you have a problem, help us out. Start out with I have a 454 with ???? hours, here is what I have done, what else????

Are you having issues with your browser loading the most recent posts? You keep making comments that make it seem like you haven't read the prior posts.

To your comment, in the first note I listed what engines I have. I don't have hour meters, so don't know how many hours. I stated pretty clearly that I was looking for ideas on how to diagnose the issue that I described. I had not taken any action to rectify, so there was nothing to tell you about.

Seriously, your note confuses me.
 
How many gas tanks do you have? I had a similar issue but only when I was using the port tank. If I ran the engine off the auxiliary tank, it ran fine. It was he anti-siphon valve on the tank that was the issue. Worth checking, for it was an easy fix.
 
There is a way to tell if you have a reverse running engine or if your tranny and v-drive take care of that. I am trying to remember how to tell. I am searching for it right now. But another way might be to grab the serial numbers off your engines and give Crusader a call to have them check it out.

I think there is another way to tell. Someone correct me if I am wrong, but when you find the metal plate with the serial number, it shows the firing order too. Check to see if they are the same, then you know the engines rotate in the same direction. I thought Carver only used engines with the same rotation and then used the tranny/v-drive to make the change. I know mine are identical. I can swap my carbs, distributors etc. for testing purposes.

I'll keep looking, but I know there is a simple way to figure it out.

I used a far less sophisticated method to determine this.
I have the original build sheet from Carver and it list the starboard engine as RH, and port engine as LH.

2 tanks.
I'll check this.
I like easy fixes. :)
 
That won't tell you that for sure. Mine say the same thing and I know for a fact the engines are identical turning. The metal plate on my engine even has the same RH and LH on them. I think all that really means is the port vs starboard engine.

Good to know! Thanks! I'll be at the boat tomorrow night and will verify in person.
 
just came in from working on the GM V8 in signature boat. Looked up the cap and rotor that you listed and noticed the rotor contact is NOT spring loaded to the center contact of the CAP. This probably means the center contact of the CAP is a little carbon "brush" with a spring (like from a ballpoint pen) behind it. Engine was missing and I found the spring had failed. Probably rusted out, but not pushing the center contact into solid contact with the rotor. Push on the center springy thingy and see if it's springy.
 
I would give the engine a complete tune up wire, plugs, you should have a module, coil and rebuild your carb. I did it every 3 years. I also change fuel filters begin and middle of the year. Your engine sounds to me like fuel, carberator needs adjustment your jets can be dirty and inline filter. Just have someone rebuild it for you.

Yep, thanks. With the distributor conversion kits the ignition system will be done. Agreed that it is time to do the carbs also. Changed fuel filters end of last season, but thinking of upgrading them.
 
Changed the port engine distributor capacitor over the past weekend. Didn't take the boat out to test it under load, but I did run it for about 30 min at the dock and it ran perfectly. Hoping this solves the issue in the short term so that I can use the boat while waiting for the new EST distributor kits.
BTW, I confirmed that my engines ARE in fact counter rotating. After reading Craig's comment above I was concerned that mine might not be counter rotating.
 
You really need to test this repair by taking the boat out. Idling at the dock will prove almost nothing other than the part you replaced was installed correctly.
It sounds like you need to run the boat under load for about a half hour and then tell us how it's running?
