My 2020 is starting finally...

[1966Mustang]

Apparently, we are overheating. I am just about done with this MCM 170.
Decision time.

Can t help with the I/O issues, but the teak looks great. I used cetol on mine , lotta work, but I can get about 5-7 years before doing it again.

Good luck with your decision

This has been on the 'ignore' list, but it doesn't have oil pressure when hot - that's indicative of something way down in the rotating assembly, crank journals, bearings, etc. Well, so much for the magical thinking approach.


Too Soon! It wasn't supposed to do anything 'wrong' today. I mean.. at least run like a top until the bellows go and sink at the launch.



Popped the valve cover and valve springs in rear are 'a little rusty', which would jive with the erosion/water leaking into that port when I first got the boat. This is the first time I've popped the VC... :D



I feel like replacing/rebuilding the head, maybe it just needs a valve job. I've replaced about everything external on it. - Cam snout resleeve, good used exhaust manifold, new upper reservoir, carb rebuild, fuel pump rebuild, alternator, pertronix, etc etc etc.



No one wants to work on this thing here in VABeach area (that i know of). Even the budget boat boys said - 'that engines getting a little long in the tooth ain't it?'. So, the option is - I get to do the wrenching, and bring it to a machine shop. IDK. Just venting.



A bracket and outboard? Well, that would be quicker but way more expensive. What angle bracket, length shaft, and what HP? I'm sure it's all in this board someplace.


Am going to have to sleep on it, discuss with SWMBO. I've got way more into this that I'm going to get - but I do like it.



Those economics don't jive with SWMBO who asked "Why don't we just rent a boat when we want to go out?" .



Other than it is against every fiber of my being? I like pain? Because I want to sit at the dock and drink beer? In my boat... which I haven't been able to do since getting this thing...


Feeling kinda dejected with the 170. I'll keep calm until opportunity presents herself.

If it’s overheating and you have a closed cooling system, it’s probably leaking coolant out of the water pump seal. I had to sleeve the front end of the cam shaft (it’s integral with the water pump and not real easy to access). You need to pull the harmonic balancer, which houses the alternator (though by now you may already have an aftermarket external alternator installed).

I think it’s a good engine if it’s in good shape but if you have to bore it out, buy a bunch of parts, probably including all new rubber on both sides of the transom, this is exactly the time to consider bracket and outboard.

Did the waterpump/cam seals last year - that fixed that particular issue. Starting up this year for the first time it dripped a couple of times out the weephole then stopped.

I'm going to take a deep breath here and look at the easiest things...



- Inspect the oil, disassemble the oil filter, see if there's anything sparkly to see.
- If sparkles in oil... have a bigger conversation.


- If no sparkles... then change then oil with some rotella 15w40. Check compression. Go from there.


The comment about the cam bearing service part is interesting: http://www.wellcraftv20.com/communit...5&postcount=55

Tough decisions, and ones that unfortunately I can't give you any sound input other than hoping that you can work this out. I can sympathize about not doing anything in this heat. The Pipe Dream is sitting in her slip, waiting for me, but it was so hot this past weekend that I punted going out.
