“Outboard Won’t Start? Replace the Carb (Tohatsu 3.5HP Fix)”
If your outboard won’t start, won’t idle, or just refuses to run properly… there’s a good chance the carburettor is the problem.
In this video, I take you step-by-step through replacing the carburettor on a Tohatsu 3.5HP 4-stroke outboard, including removing the old unit, fitting a new one, and explaining why modern carbs are often easier to replace than repair.
Modern carburettors are effectively tamper-proof—tiny jets, sealed components, and emissions restrictions mean even a small amount of dirt can stop your engine running, and cleaning them isn’t always practical. In many cases, replacement is simply quicker, cheaper, and more reliable.

Moving on.. She’s back!! 😁♥️😁
In this Weeks video, we take a look at the market in St Georges bay. Has it changed or is it still the same? We take a gentle sale round from St George's Bay to Manoel Island. I go to the childless to pick up some gear and the boat gets a jolly good tidy up why because Cindy is on her way back....
