Sean,
What's he saying is wrong with the distributor? 

Manyhave been going the DUI route:

As Pete mentioned above, the DUI (Davis Unified Ignition) is a very nice option.  You can check them out on their website:  https://performancedistributors.com/product/marine-dui-distributors/

It is likely that your engine is a reverse-rotation (RR) configuration.  One way to double-check is to look at the metal identification plate from PCM.  Another way is to observe the rotation from the REAR of the boat, looking forward.  A "standard" or left-hand rotation will turn counter-clockwise when looking from the rear.  If your engine is a RR or right-hand rotation, it will turn clockwise when looking from the rear.

Assuming a RR engine, the D.U.I. distributor part number for a 351W small-block Ford in reverse-rotation is: M35820RRRD.  The last 2 letters indicate the color of the distributor cap.  I.e. RD=Red; BL=Blue; BK= Black, etc.  Go with the red cap as red makes the boat faster.

Hello all, and thanks for the information. About 3 years ago the boat ran rough. Took it to a mechanic and he said a spring was broken in the distributor. Prior to that a mechanic replaced my carburetor back three times when it was really a distributor timing issue. Now the screws won't keep the cap tight. Put a new cap and rotor and it won't start. Put the old cap and rotor on runs bad. Needs a new cap and rotor but I've had so many problems with this distributor I'm thinking replacing all the same time. Just be done with it

 A new distributor and a carb re-build and you should be good-to-go.

Great info and thanks.  Huge problem now is that everyone that sells the DUI is sold out.  4-6 week wait for one.  Looking that the Pertronix ones now.   But those are hard to find also.  No fun trying to find out.  Dam.

Here's a link to one that's not a DUI but it is an HEI for a 351W with the reverse rotation gear Wink

Never dealt with the place, they posted here on CCF once, a few questions were asked and ......they never got back with any kind of answers.

It says they have one in stock.

Pertronix doesn't sell a bolt in Reverse Rotation distributor for a 351W, just a normal rotation with the wrong gear.

AAA marine in the same link as above sells a gear that could be used with a Pertronix, you'd have to do the swap yourself.

Here's a link to a recent (2020) thread and there's a link in that thread too

Since then they've started selling the RR version.
