Is there such a thing for us long suffering Holley owners?

If not any advise for long periods of not using the boat (Florida Winters) Nov-Mar?

Thanks

Yes there are efi conversions out there but its probably not worth the hassle, just sell your boat and get a newer one already equipped with efi, or buy a new, not a remanufactured 4160 and be done with it.

The efi conversion "carbs" from Holley start around $1800 and are pretty much plug and play. I spent $2000 on my 81 and believe it or not, I like working on the carb. BUT an LT1 205 will be my next boat if I don't put an LT1 in the 81.

Those automotive ones are closed loop systems using o2 sensors, not saying it can't be done but its cost prohibitive, manifolds, fuel systems, wiring, ecm, etc.

It can be done, but most people who know more about it than I do will tell you that it's not worth the money or trouble. For the winter, just a good marine stabilizer or SeaFoam and, if you can, start the boat up on a hose once every month, run it for a few minutes, and drain again. Fresh gas is your friend.

Thats what I do, I put more hours on my boat this year by running in the driveway to ensure it stays running right then I did on the water so far this year...:rolleyes:

Am I missing something? Why would you store a boat from Nov-Mar in FLORIDA? In Wisconsin we ski from April to Novemeber. I would think you should be out year round, or at the most miss from mid December to late February? Maybe you're traveling for work or something?

Most block freezes occur in the south.

Thanks for all the advice
yes work keeps me very busy this time of year during the holiday season. That's not to say if the there is a warm saturday in December or March that we do not go out for a quick run,

I will keep up better on starting it up on the hose as well, only takes a few minutes and it sure sounds like it curbs alot of headaches.

I did have the carb rebuilt just recently, however starting it up yesterday required pouring gas into the carb. Is this a result of the rebuild?

After this summer, I am at my whits end with this thing. It spend way too much time in the shop and I spent way too much money. I really enjoy this boat, however I am now forced into considering either a new EFI LT-1 or a new boat. The new 4160 suggestion sounds viable as well.

If you had to pour gas in the carb to get it to start, you either don't have the choke set rich enough, have poor accelerator pump operation, or didn't give a couple strokes of the throttle to give the engine some gas to start with (and thereby set the choke).

If your current boat does everything you need it to do, why spend 15k + on a newer one with efi, if its me I would buy a new carburetor and your reliability issues are solved.
