    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...

    Wet-v-Dry tune up adjustments on MC165 I6

    Hi all... So I have my boat up and running well so far. One pump of the throttle and it fires up and idles without hesitation. Ran it up to 2500 RPM...immediate throttle response and no signs of stumble whatsoever. I've set the dwell(31deg) and the idle(580RPM...in gear). I know I need to...

    Priming fuel system Mercruiser 165/I6

    Hi all... I replaced the carb(new Rochester 2GC), installed a new fuel filter in the mechanical fuel pump, and installed a new fuel/water seperator. I filled the seperator filter with gas but I need to know how to prime the remainder of the system as I'm getting no fuel to the carb. Thanks in...

    Merc 110(9.8Hp) Impeller replacement

    Had the Panfish Slayer out and figured that I should replace the water pump/impeller this year. I've never done it, although my father(who bought it new in about 1974 or so), always had it serviced regularly. There are no issues with it, and I do get a good stream of water...but, "an ounce of...

    Prop ???'s for Inline 6

    So I was reading the factory manual (from 1973) last night...which is the year of the motor in my 1985, 19' Wellcraft. Just reading about the prop recomendations in the appendix...and it stated that a 17-19' boat should turn between a 14.5 and 15.5 inch/21-23 pitch Aluminum prop. I'm running...

    Outdrive pressure testing

    I've got my drive back together and would like to pressure test to confirm all is well. I'm assuming most of the testing equipment is homemade, so what seems to be the favored method/design? I have a compressor and/or a bike pump, as I've heard of both being used. I'm currently away from...

    Alpha one lower unit fitment

    A local guy has an Alpha one lower unit for sale...price is $200. He says it's in good condition with only a little normal scuffing on the skeg. He didn't state whether or not it's from a "Gen 1 or Gen 2"... I know the upper units are different, are the lower units interchangeable, and is...

    Pertronix ignition conversion for Mercruiser 165 I6

    I've read many posts regarding the conversion from points. I will be purchasing the Pertronix Ignitor II(91163A). So... What modifications to my coil-distributor wiring do I need to make? I've read that I DO need a new coil... I've read that I DON'T need a new coil. Soooo...whats it...
