Hi.
I have a 4hp Johnson engine (BJ4BRCCS - serial# 7641969) which I believe is a 1988 model. I'd very much like to increase the prop pitch or diameter to get a little more grunt and a little less thrashing. I'd also quite like to use a remote fuel tank so that I'm not having to stop to top up every 3/4 of an hour or so.
Are either of these things particularly difficult to achieve? I'm not at all sure whether my engine has a mechanical fuel pump or not and a web search for "johnson 4hp propellors" just leaves me more confused than ever.
I'm in the UK, if anyone's in a position to post a source for a new prop and/or suitable fuel line adaptors/whatever. I'd much rather make these changes to my johnson than get a different motor if at all possible since apart from those two niggles I've been perfectly happy with it.
Happy boating everyone.
Colin
