While it's out an apart suggest you check the cone to be sure there is no unusual wear there.

I did it just like you described, with two small changes: 1. I used a car scissors jack under the engine to support it - worked fine. 2. I spent 4-5 fun hours getting it out, but maybe that's just me ( near retirement age, I found it challenging to maneuver myself in there to get some wrench or other on the various bolts... with enough torque or impact to break them free in the confined spaces ... and I had no previous experience). Neither of the mechanics I was able to find in my area would do the removal, so it was mine to do. I'm having one of them do the front and rear seal replacement - the rear seal is the current leak problem - it was insulted a few years ago when the bilge pump hose jumped up in the air, grabbed the spinning shaft bolts, and wrapped its wire into ~1000 turns pressing tight into the rear seal...... I may try to do rear engine crankshaft seal replacement too - my small oil leak seems to be coming from there and its accessible now. Fun stuff ....but many thanks again for the clear instructions, Nate Flesness "Sarah Jean" 1980 30-1 Siskiwit Bay Marina Lake Superior From: dre...@gmail.com [mailto:dre...@gmail.com] Sent: Wednesday, August 01, 2012 12:17 PM To: cnc-list@cnc-list.com Cc: Nate Flesness Subject: Re: Stus-List Transmission Fluid leak (Yanmar 2qm15) Hi Nate, I am in the middle of rebuilding my 2QM15 which came with my C&C 29 mk1. I disagree that the engine needs to be pulled to get out the transmission. You can pull the transmission without pulling the engine. You will be surprised, but the 2QM15 transmission weighs only about 20lbs. But since the rear motor mounts bolt to the transmission, you will have to support the rear of the engine. This can be done by either stacking boards under the oil pan (use wide boards) and/or using a block and tackle to lift from your boom. Connect the tackle to the middle of the boom with some good rope, then bring other end of the tackle into the cabin/engine compartment connecting it to the rear engine lift ring which is on the rear of the cylinder head. It easier than it sounds, and it should be a simple job. I would leave the engine mounts connected to the transmission unbolting them from the stringers. That way you do not change the mount adjustments keeping your engine aligned when returned. I pulled my engine out single-handedly using my boom, main sheet, and vang block and tackle. I first pulled the engine onto plywood into the cabin. I then removed the transmission thinking it would reduce weight, but was surprised by how light it was. Using both blocks systems, I lifted the engine up, out, and swung it over and down onto the dock next to my boat. Using a 2X4 looped to the engine lift rings, another person and I walked the engine off the docks. The 2QM15 total weight is about 320lbs. - Paul E. s/v Johanna Rose Carrabelle, FL On Aug 1, 2012, at 12:00 PM, cnc-list-requ...@cnc-list.com wrote: Date: Wed, 1 Aug 2012 14:37:20 +0000 From: Nate Flesness < <mailto:n...@isis.org> n...@isis.org> To: " <mailto:cnc-list@cnc-list.com> cnc-list@cnc-list.com" < <mailto:cnc-list@cnc-list.com> cnc-list@cnc-list.com> Subject: Re: Stus-List Transmission Fluid leak (Yanmar 2qm15) Message-ID: <3D3EC17E62A20F4C8771D26B7C513853114539C0@BL2PRD0510MB385. <http://namprd05.prod.outlook.com/> namprd05.prod.outlook.com> Content-Type: text/plain; charset="utf-8" After a couple of years of small drips, my 32 year old Yanmar started leaking transmission fluid at an ounce an hour while motoring last weekend. Probably from the forward seal ? where it meets the engine. It?s the big flange ? I?ve tried to get in there to tighten bolts but not been able to move them with the little wrenches I could get into the small spaces. Dockside advice is I?ll have to have the engine pulled. Meanwhile I?m stopping, checking and filling every 2-4 hours if motoring to keep the tranny fluid at normal levels, and catching the leak in a dishpan under the engine. Any ideas? If I?m paying for engine in and out, what ELSE would people recommend? I?m thinking possibly motor mounts?? and I?ve always had a small oil leak too (I know, they say Yanmars never leak?.).
