Romany 162 Posted April 10 Share Posted April 10 Just been guesstimated between $1500 & 1800 to sand blast,pull a 3gm30f raw water pump apart, and fit 2 new bearings and seal, repaint. I supply the bits! I think they are taking the piss. Anybody know an engineering place i could try for sensible pricing? I have removed the pump from boat so no farting around.

aardvarkash10 969 Posted April 10 Share Posted April 10 I think they put the decimal point in the wrong place. 1 Quote Link to post Share on other sites
Romany 162 Posted April 10 Author Share Posted April 10 Yes i was disappointed with that reply. That the pump is off a boat meant i was handed onto the marine guy. Clearly cos its a boat its so much more complex. Quote Link to post Share on other sites
aardvarkash10 969 Posted April 10 Share Posted April 10 Is it the raw seawater pump, or the engine pump? Either way, you can get a brand new replacement for 25% of that repair cost Quote Link to post Share on other sites

Just rebuilt 2 of them from the gm series, think it was $80 for 2 seals, 2 bearings, 2 gaskets and one impeller. You can rattle can them if you like but being bronze why bother? Remember to lap the faceplate flat with some wet and dry on a sheet of glass and you might need a type of bearing puller that levers the two bearing apart Its all pretty basic 1 Quote Link to post Share on other sites
mcp 32 Posted April 10 Share Posted April 10 Have a look on parts4engines.com whole new raw water pumps are very very reasonable from them. Quote Link to post Share on other sites
Black Panther 1,591 Posted April 10 Share Posted April 10 I had a failure last week. Not a yanmar. Replacement $1250. Gut with a workshop repaired the old one $30. Quote Link to post Share on other sites
K4309 269 Posted April 10 Share Posted April 10 You can get cans of suitable enamel spray paint from many suppliers, including from Bumblings, budget about $30. A piece that small you could clean up without sand blasting. Wire brush, or a small bit on a dremel. If you don't have a dremel you could buy 5 or 6 for the cost of getting someone else to do it. Service kit you are supplying already. Just need to work out how to push the bearings - not complicated. We spray painted our old engine, and many of its components, it lasts fine. We went with a nice gold colour, to reflect the total cost of maintaining a boat Quote Link to post Share on other sites
waikiore 400 Posted April 10 Share Posted April 10 Did my one just before Christmas, genuine seals -and the bearings from a bearing shop about $150.00 for parts and two hours work (including making some timber shapes to press it together) Quote Link to post Share on other sites
Pecco 10 Posted April 11 Share Posted April 11 I can confirm I fixed it myself for about $150. Checked some info in other forums and ordered the parts from the US. From memory the diameter of the seal is 12mm, not 13 like stated in the post. You can actually buy the all assebly and just stick it in.

mischief 3 Posted April 11 Share Posted April 11 just did the lip seals, and two bearings on my 2ym15 raw water pump. was easy and cheap. use a press to get the bearings off the shaft, but just tapped the new ones one. hardest part was finding someone to sell me the parts locally, and pressing the old front bearing off which had corroded onto the shaft somewhat. got the seals, bearings etc here in the end https://www.lhmarine.co.nz/collections/johnson-pump Quote Link to post Share on other sites
Psyche 634 Posted April 11 Share Posted April 11 its not rocket science Quote Link to post Share on other sites
Romany 162 Posted April 11 Author Share Posted April 11 Yes I am willing to try it myself but I don't have a bearing press, and so think I would have to resort to primitive procedures - like a f...ing big hammer to remove the bearings . I have yootube too, and of course it looks simple enough. D2 has a mechanical boyfriend so I think I will get his help and do it under supervision 2 Quote Link to post Share on other sites
