    Re: Alpha 1 Sterndrive Compatibility w/ a 70's era I6 Motor Welcome!Lol!! I had an issue with the elbow and the original pipe being offset about 3"...but only had about 4" of vertical clearance between the two(You can pick it up slightly in the first pic...). The PO used two heavy...

    Strange Trim up problem...

    I was out today and noticed something a little strange...I was in a no wake zone and when I throttled up-started trimming up, the motor cut in and out in conjunction with the trim pump running. I then looked at the volt meter and saw that there was a significant drop in voltage everytime I...

    Rochester Carb issue??

    Re: Rochester Carb issue?? Here's what I found............. after getting into the carb...what appears to be a tiny metal shaving which was not allowing the needle to seat. As long as I have it apart I'll go ahead and check/clean everything else. Good call "Series 60"...

    Rochester Carb issue??

    My previous posts dealt with my hard "hot" start issue... In my troubleshooting I've found a bad battery, which may not have been the primary culprit. I put a secondary battery in it, just to start it cold...and when I shut it off I immediately looked into the throat of the carb. I noticed...

    Battery...Marine Starting or Deep Cycle?

    In my previous thread it was discovered that my battery is more useful as a doorstop...so it's off to find a new one. What do I need? What are the differences(other than price)between the "Marine Starting", and the "Marine Deep Cell"? Mine is used primarily for starting...however I do run a...

    Hot start issue...

    So I'm out today, ran around for about 20 miles then decided to stop and swim. We pulled in to where we THOUGHT it would be good, but found out it was weedy. I said, no problem and figured we'd move about 200 yards closer to some more boats and went to start(after sitting for about 2 min)...

    Tach gremlin...

    Hi all... I installed a new Faria tach about 3 months ago, the old one was toast. This one is new and functions well up to 3k RPM, but when throttled up above that it pegs out only to return to "normal" when throttled back down below 3k once again. There are 4 positions on the selector on the...

    Compression readings...

    Just did a compression test. I read 135lbs on 1,2,5,6...140lbs on 3,4. Done with all plugs out, engine at OpTemp, 4 complete revs each, and WOT... I know these are within the 10% variance, just wondering what is considered "low", "average", or "new" would be. No running issues...just for my...

    Running observations...Inline 6

    Hi all... Out today and noted a couple of things: 1. Temp gauge reads around 190 when running around...but the water dist box/brass sender reads no higher than 160. Even after I took it out of the water, I checked the temps again. The temp gauge still reads around 190...but the highest temp...

    Temp gauge testing...

    Hi all... After getting my engine running and my Hi-Temp silicone exhaust hooked up, I bought an IR temp gun to spot check for hotspots. My temp gauge remains at a constant 175(on muffs), but when I hit the actual brass sending unit with the light...it showed only 145. I allowed the engine to...

    Coil resistance values...

    Primary: 1.8 ohms(+ / -) Secondary: 13K ohms(both pole/+ & pole/-) The reason I ask, is that I've noticed it getting quite warm, and until a couple of days ago...it was running with 12v as opposed to the 6v it's supposed to. Don't know if there was any internal damage done.

    Timing question...Inline 6

    Does the rotor point directly at the #1 wire terminal with the points open when #1 is at TDC?. I'm installing a new distributor and need to get the allignment correct.

    Coil resistance wire dilema...Inline 6

    Hi all... I have points and I don't THINK the previous owner installed a reistor wire when the swap was made. I just remember seeing something that didn't seem right, but was buried under multiple layers of electrical tape...only the ends were exposed enough to see. As this is a "composite"...

    Acoustic engine compartment insulation

    My engine hatch has no insulation...any recomendations for some thin material to install? I'm thinking something along the line of what my small outboard has inside of the cover...small cell foam material with an adhesive backing.

    Manifold replacement on MC Inline 6

    Hi all... Just looking down the road here. I just bought a new elbow for my 160(the elbows are NOT interchangeable with the 165) and have my boat running/cooling well. However, IF, down the road I need to replace the manifold will the commonly found 165 manifold bolt right up to my block...

    Prop dia-v-pitch effects

    Hi all... So I was given a 15" 17P 3 chopper from a friend of mine. I'm currently running a 14", 19P. Boat specs in my Signature... So a couple of questions. Assuming this clears the trim tab, what will the performance difference be? I'm not using this as a primary, but rather a...

    T-stat or not T-stat...

    SO... I'm going to start a mess here I'm sure, but here goes. Seeing, reading, and hearing all of the problems associated with overheating, due in many cases to faulty T-stats. Why is there a need for them in a boat which is running on "warm" water? I understand the function in a vehicle...

    Mercruiser165 exhaust dilema...

    Hi all. In the immortal words of Maxwell Smart..."missed it by THAT much." I thought all was good now...tuned up running and ready to go, so I thought. With a little time on my hands, I decided to check the water shutter. So, I took off the elbow, pipe etc...and found NO, shutter...

    Rochester 2bbl carb compatability...

    I was out and found a "mans" rummage sale, so I stopped. I found an old, in good condition Rochester 2bbl carb(with two adjusting screws and automatic choke)which looks identical to the one on my boat. So my questions are: 1. Can I rebuild this and keep it for a spare? 2. If so...is there a...
