It was done as a clearance issue. Clearly on my 42 DC and the 47's there is plenty of room for a standard cap. Not sure on a 38,35's or the 31's that had the 300's in them. It would facilitate a rotor change and probably an attachment alteration. I was going to work on it but have so many spares that I have never gotten to it.

Sounds like a clearance/starter alignment issue. Shims might do the trick. I would look at the flywheel teeth if you can and be sure they are ok. Also make sure they are not somehow out of alignment

I too would patch the area. Too extreme to remove all for me. I would drench the area in CPES. Then start to patch. It’s a very small area. Epoxy and mahogany sawdust make a great filler.

Hello. Did you move the timing. This is a very odd symptom. When you say destroyed. Spring. Teeth?? Standing by

Hard to know what the breaker looks like behind but I would start with Blue Sea’s. If you pull the panel you might find names on the breakers

So happy for you Whitney. Boat looks awesome without the bridge.

I run Rotella T 40. I also add this zddp additive.

Very cool old Roamer. They run very wet. It’s the old hull. But ultra cool.

Hello William. Is it the one that goes between a vertical surface and a horizontal one? About 3/8 wide.

Yes yes yes. The LS at the end of the part number means lobe sensing. I have had mine for 10 years. They are awesome.

A 47 can be moved over the road. However, if she has a bridge, that has to come off. Probably the top and side windows and windshield must come down. Additionally, she has to move with permit, chase cars and can only move during daylight hours. Looked at it many times and just could not make the dollars work.

Jim, That is a really good idea. That will definitely work.

John, I would say yes< BUT, I am not sure about the direction of turning. One tooth will give you are adjustment if you are limited by physical constraints of the distributor

The dimple is on the flat part of the flywheel. Those teeth are on the flywheel.

I would say 1/4.

John. Just so you know what you are looking for. It is basically a drill mark tgat is just the start of a hole. Round and not deep. I always try to put a drop of white paint on mine when I can get to it. It makes timing so much easier

I have always wanted one. Only about 20 or so made. Hard boat to handle lines on. Especially aft. Many of them seem to be on Great Lakes. Soft top version is really cool. All had 427/300’s. Should run well tight working on the front of the motors.

Kowboy, Your profile says Detroit Diesels. Please do not curse on this forum. We are here to help each other.

John, I texted Lee for you. He should chime in.

Kowboy. Look above at the third post in this string. I asked if they were Cummins 370's. Your response was Yes.
