Sean, What's he saying is wrong with the distributor? Manyhave been going the DUI route: https://www.summitracing.com/search/brand/davis-unified-ignition/part-type/distributors?N=part-type%3adistributors&autoview=ProductName&SortBy=Default&SortOrder=Ascending&tw=davis+&sw=Davis+Unified+Ignition&utm_source=bing&utm_medium=cpc&utm_term=DUI+distributors&utm_content=Davis+Unified&utm_campaign=Brands+D+-+L+%28Search%29" rel="nofollow - Davis Unified Ignition Distributors - Free Shipping on Orders Over $99 at Summit Racing ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

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. JQ

| 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  http://aaamarine.com/marine-electronic-ignition-distributors/marine-351w-hei-mercruiser-omc-reverse-rotation-engine-distributor" rel="nofollow - link 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. http://www.correctcraftfan.com/forum/forum_posts.asp?TID=49848&KW=distributor&title=found-rev-rot-ford-distributor-gear-500" rel="nofollow - link
