I am having a heck of a time lining my motor back up. I have engine serial number 0w038097 and out drive 0w251759. I have spent two days of the last two weekends tediously raising and lowering the front engine mounts trying to get that alignment bar to slide in easily, the two finger slide as I have been reading about. I can get it to where I have a decent grease pattern but it takes "effort" to get it in and out.
Little back story, I had a leak around my transom plate so I pulled the motor (350 MPI Horizon) out of my 2006 rinker 270. I don't know anything about previous maintenance, there were no records. The boat showed having 100 hours on it, I have had it four years. I figured even if he did nothing, I was only about 50 hours behind any given maintenance need so I bought it. Only problem I have really had is a blown coupler so I'm already suspicious of the set up. It's been down 2 years fixing the transom plate and now just getting it all back together.
I feel like the motor is just not sitting right for some reason. I have raised and lowered the motor, I get the grease to go from scraping the top of the tool to scraping the bottom and when I get a decent pattern, it is still to difficult to push the tool in. I have never done this before so just going by what I'm reading on sites, this is not good enough.
So, I start looking at the rear engine mounts, couple of things occur to me. So you have a motor sitting there with a coupler, you have a transom plate sitting there with a bearing and you have front motor mounts to adjust the angle of the motor to hopefully allow the tool to slide in. So how is that bearing and coupler aligned to the point you have only the minor adjustments of the front mounts to get it perfectly straight? When I put the transom plate back on, it was kind of fixed through the holes in the transom but hard to imagine those holes where they are drilled have any relationship to where the coupler is sitting? If the center of that bearing is a little left or right of the center of the coupler, it would never line up! Not getting that.
So, I look at the components of the rear engine mounts. They are pretty much the same for the serial number I have and for the serial numbers just below but I am seeing some discrepancy and I don't see an assembly parts drawing to show how the fly wheel cover and the transom plate sit together with the through bolt, spacers and washers in place. I assume all the washers, spacers and such go on the bolt before it goes through the flywheel mounts and then into the nut on the bottom, correct? I have it assembled with what would look like the right parts for my serial number, however, the washer under the head of the bolt is not tight against the fly wheel cover, like the engine could move up and down 1/.16" or so, is that right???
I have 3 parts drawings attached, one is for the flywheel for my serial number which also shows and calls out the bolts and such for the engine mount bolt. Then, I have two different parts drawings for the transom plate and shift cable which calls out for slightly different parts on that bolt. Oddly, one thing I do notice different is the one for 249999 and less, the bolts on the steering pivot bolts have their own washer with bend up tabs to lock the bolts, The one for my serial number shows one part that is kind of a handle shape that has the tabs on each end of it...kind of odd they don't match. Mine has the individual tab washers with is out of my serial number range.
So, the difference I'm focusing on with the parts is number 7 and 8. If you look at the flywheel drawing it calls out a part on part 8 that is a big spring lock washer looking thing. I did not find that on my boat when the motor was pulled. If you look at the parts drawing for 24999 transom plate, it also shows that lock washer but my serial number is 251759. When you look at the transom plate list for my serial number, that lock washer is not there and another SS flat washer is there instead. None of this would make any difference if all these parts and pieces go on the bolt before they go through the flywheel housing. But, for example, if that spring washer goes between the fly wheel tab and the tab on the transom plate then that would change the position of the motor and the ability to align it. What the heck do I have here? When I went through the parts I had when the motor came out, I had the bolt, a washer, a spacer and the fiber washer and that was it so someone screwed this up before, perhaps when they did the coupler or this was the reason the coupler failed.
