Graham Nash Posted March 8, 2022 Report Share Posted March 8, 2022 Good morning, my boat is moored up wareham river which (it would seem) is relatively fresh water. I antifouled it a couple of years ago and it has been in the water since. Most small boat owners said at the time that they only do theirs every 3 or 4 years because of the lack of need. My boat is out of the water at the moment and they are right, there is no build up on the hull and it looks pretty good. However, while its out I'm considering refreshing it again. Do I need to remove the old stuff first (because that will be the deal breaker as to whether it gets done again or not). Many thanks.

Brian Posted March 8, 2022 Report Share Posted March 8, 2022 The antifoul on mine was in good condition, so I pressure washed it and re did it. fisherman1055 1 Quote Link to comment Share on other sites More sharing options...

great white Posted March 8, 2022 Report Share Posted March 8, 2022 No need to take it off Graham we would usually rub it flat and make sure there are no flaky bits , then give it one coat all over. Good to use the same brand of paint if you can. A couple of things to be careful of; 1. The sacrificial anodes, fresh water ones are not zinc. Which is the usual material. 2. The water system will be full of fresh water not sea water and the freezing point is much lower. system may need to be drained or run in an antifreeze mix. fisherman1055 1 Quote Link to comment Share on other sites More sharing options...

Im not sure I have any anodes Charlie, the outboard is tilted out of the water once I moor up and the power is disconnected completely (do I need one)?

Brian Posted March 8, 2022 Report Share Posted March 8, 2022 My motor has an anode under the mounting bracket, which is always in the water. There are also anodes in the water jacket. Graham Nash 1 Quote Link to comment Share on other sites More sharing options...

There are also anodes in the water jacket. yes you're absolutely right. I have a large one under the mount, and two beneath the skeg. Mike (Fishermans Cafe) explained their purpose while I was devouring a large breakfast this morning :-) Stuie, Maverick Martin, Jim and 3 others 3 3 Quote Link to comment Share on other sites More sharing options...
