Does anyone run a gallon of Plumbers anti freeze through the rabbit ears until the pisser and exhaust is running pink? I know that engine hasn't any pure water in any nook and cranny that could freeze and split anything over the winter. It takes a few seconds to run a gallon through. I forgot to say that I do that. Simple to rig a small length of garden hose to the muffs and to cap on the jug. Start the engine, hold the jug upside down and stab the bottom with a knife. It takes seconds to run a gallon through. Discharge from the pisser will turn pink and the exhaust will run pink. Shut off engine, point the engine to the north wind and sleep like a baby all winter.
@WhatsthePoint... The extra insurance certainly can't hurt nothing especially if the boat is stored outside for the winter. I personally don't but mine is stored inside my 700 sq. ft. garage year round where it never freezes.

Where can I find this product.I always use a product called K100 S+ which totally eliminates water in the fuel as it actually it makes water burn among other things. It's available at CTC and has always eliminated any fuel problems that pop up at season start-up for me. I used to use Sea Foam but found the K100 much superior for curing bad fuel problems.
Hope this isn't your problem but is your Yamaha 4-stroke fuel injected? If so your problem could be the VST filter (Vapor Separator Tank) which are notorious for plugging on Yamahas especially when bad fuel is involved. Ethanol currently 10-15% blended into our Canadian fuel is also a culprit in fouling these VST filters. Fouled VST filters cause the problem you are describing exactly. I would try the K100 first as the injectors could also be fouled. The VST filter change out is expensive when done at the dealer because the filter alone is in the neighborhood of $70 let alone the labour involved. You can Google it as there's lots of information on this problem in Yamaha EFI outboards. In some cases it can be cleaned but usually needs to be changed. Here's a video how to change it, it's for a F115 Yamaha but the procedure is the same.
But try this first, hopefully that's all that's needed.

Buckhorn... had 84 same as your/s... sold it.. then it was stolen. great motors... Red..
I said in the post CTC which is Canadian Tire. They have small bottles 237 ml or large bottles 948 ml which is the better buy and lasts me for 3 tanks of 70L of gas for 3 spring start-ups. You can also use it periodically during the season but I have never found a need to.
