    Test stand running 70's 350 water hook up

    Thanks for the reply, Yes, the valves while running is messy 👎 I went by the book after stem seal replacement, but when finding TDC, #1 exaust seemed a bit tight. I want to recheck after the run. The main goal is the timing and once warmed up, the compression test. I have an infrared temp...

    Test stand running 70's 350 water hook up

    Ok, it's not really a test stand. It's sitting with it's mounts on a heavy duty dolly. I want to start it to test compression and adjust timing and rocker arms. Question is; how to get water to it? My idea is to connect a garden hose with a Y to both hoses at the back of the exaust...

    Hard to turn crank while rebuilding GM 350

    Think I got it. Mains mic just as Plastigage shows 1-4 = .0015 and 5 = .0018 The connecting rods had problems With STD bearings measured .001 and less a little With old oversized measured .002 plus a little. Going to get some .001 X of same brand and see if I can mix half and half with the...

    Hard to turn crank while rebuilding GM 350

    I'm thinking more of a warped block from not being winterized. Have not measured anything yet, the only place that had micrometer and calipers in stock was HF. Going to go get better today. After starting to disassemble, dug old bearings out of scrap pile to double check sizes. Gave wrong info...

    Hard to turn crank while rebuilding GM 350

    Guess I should have mentioned this engine didn't die from oil starvation or overheating. Here in Michigan most cracked blocks are from freezing. The water in the cylinder came from a cracked exaust manifold and leaked past the open valve then sat in there for 15+ years. Thus seized piston. The...

    Hard to turn crank while rebuilding GM 350

    I never did mic anything since I thought I was putting the same sizes back in. It's been a year or two since I did it, but if I remember, the top mains were the .005 under from the factory. (Replaced with all new Clevite) When I take the caps off and inspect the bearings, I see a shine on the...

    Hard to turn crank while rebuilding GM 350

    I know, more time on my hands than brains. Had the weld work on a 120 that I've been running for years since. Hopefully will work here also. The cylinder and heads looked good, no cracks, just some discoloration from seized piston.

    Hard to turn crank while rebuilding GM 350

    I started working on this motor more than a few years ago and am just getting back to it. Boat Background: 1972 24ft Starfire. Someone Frankensteined it badly. The 307 was replaced with a 78 350 and the Electric shift was geared for 120 -155 HP Motor Background: casting #3970010 F48 date code...

    Tiller kicker with controls? Possible?

    I'm stripping a 73 Starcraft 20ft I/O. This idea is for my 24ft 350 OMC electric shift. If I mount the kicker on the right side, the cables might even be long enough. The OMC is a Truetrack steering, but I have the push-pull mount from a part unit that I bet could be used to link steering to...

    Tiller kicker with controls? Possible?

    That video explained a lot! Doesn't seem so complicated as long as I find the right outboard, which is probably most in the year range I'm looking. Just some drilling and bracket attaching, not really a kit after all. The cables and control box seems like they could be any dual lever type. I'm...

    Tiller kicker with controls? Possible?

    Thanks everyone for replying, Since I'm looking for a early 1970's or older motor, finding a conversion kit made back then plus the cables and control box to fit the job is more than it's worth. I'll just stay on the hunt for a remote type model, they do show up now and then with the cables...

    Tiller kicker with controls? Possible?

    I generally fish alone with a bungee cord auto pilot while setting poles. I've been watching CL for something in my price range and year range of boat (personal weirdness for looks) most of what I see are tillers. Some are there like the 70's Twin, but usually without controls. My plan...

    What parts can I use from a 73 140hp for a 69 120hp

    Thanks for the reply. The intake/exaust manifold does look different but I don't have an old 120 laying around to compare the mounting holes or alignment of ports from engine. I guess I'll get the 8 cents per pound for the block and head, I knew there's a 120 practically behind every barn, but...

    Tiller kicker with controls? Possible?

    This might be a stupid question, but here goes. Can a tiller outboard around 10 to 25 hp be set up to be used with mechanical controls from the pilot seat? My goal is to have a trolling motor. Both my boats (150 Johnson on glass cuddy 20.5ft and 350 ci in 24ft glass cuddy) go too fast without...

    What parts can I use from a 73 140hp for a 69 120hp

    I got talked into taking an old Starcraft glass to the landfill and am stripping parts. The 140 is seized and the oil pan was full of water. As you can see from my username, I'm a packrat and can't have too many old Merc parts. So,my question is, is it worth saving things like the...

    Exhaust manifold help. Dauntless 225 with Stringer outdrive.

    Don't know if you have it figured out yet, The top connections on the thermostat housing are inflowing water and the bottom 2 are outflow. The water being pumped from the outdrive comes up through the pivot hinges through the intermediate housing to the 2 on top of it, the hoses from there...

    Electric shift upper driveshaft stripped

    Just curious, I recently took apart a high profile 225 - 245 HP drive for parts and found the water pump shaft and the upper shaft stripped. In a past thread Howard Sterndrive mentioned this as common but didn't explain why. What causes this ? It looked like a pretty dramatic failure. The...

    Late 70s 350 SBC rebuild confusion

    Thanks for all the input. I used the plate Felpro gave to block the one side opposite the choke. It has a hole in it, so it's not completely closed. I Did the carb kit, but don't have the money yet for the choke thermostat or cover and linkage. More time than money these days. Yes, I did...

    Electric shift sterndrive identification

    I'd like to know what the HP rating and gear ratio is for this drive. tag on side says Model 981231 / serial J16L (attached photo) Welch plug on top has same model number I unbolted it from a 72 350 SBC . They were in the bed of a pick up so I have no idea about it's history. Didn't see any...
