Lukecollis 0 Posted September 7, 2020 Share Posted September 7, 2020 Kia ora everyone Just new to the forum. Been a keen on fishing for years and had a few boats here and there. Now that the kids a littler older I thought I'd get back into it. Picked up a plylite fisherman on Facebook Market place recently. It had been sitting for years with no use so it was a risky purchase but a great price. Anyway, after working out they had the hand pump on back to front I was able to get her started however quickly noticed she wasn't pumping out any water. Switched her off, removed the leg and went to check the impeller and noticed that the grommet to the impeller casing had been pinched. Purchased a new grommet only to find it was still not pumping water. Checked impeller and it seemed not far off new but rubber seal on casing was flat and had a fair few groves in plate. Maybe I should replace? Checked telltale tube and its clear, checked theomostat and its free. Make sure muffs are tight on there and they seem tight. What on earth could it be? Any advice would be much appreciated! 👍 Quote Link to post Share on other sites
Island Time 1,230 Posted September 8, 2020 Share Posted September 8, 2020 Change the impellor and try again. Sometimes the vulcanizing ov the rubber to the metal drive fails, and only the centre turns around. If not that, there has to be either a blockage or the water pump drive is broken. 1 Quote Link to post Share on other sites
Lukecollis 0 Posted September 8, 2020 Author Share Posted September 8, 2020 Turned out the muffs weren't sufficient. Dropped it in a deep bucket of water and it bang there's pressure! Stoked. Now for the trim. It's slowly drops. Guessing it needs a rebuild. Anyone worked with an old unit like this? Quote Link to post Share on other sites
Dagwood 57 Posted September 8, 2020 Share Posted September 8, 2020 No offence to anyone here but you may have a better response on this forum: https://www.fishing.net.nz/forum/the-outboard-clinic_forum73.html Quite a few very knowledgeable outboard folk there. This one is more yachting orientated... Quote Link to post Share on other sites
Fogg 427 Posted September 8, 2020 Share Posted September 8, 2020 Most people here have outboards but mainly for tenders so mainly at the small end up e.g. 2.5 - 15hp. Not many people here are used to dealing with bigger units like yours hence the shortage of answers I suspect! Quote Link to post Share on other sites
Island Time 1,230 Posted September 9, 2020 Share Posted September 9, 2020 It'll just be a leaking seal - its just a hydraulic ram. Never pulled that specific model apart, but I've done a few. Strip it and have a look, seals should be available from a bearing shop.... Quote Link to post Share on other sites
