On a 1987 Mercury 2.0-liter 150-HP some of the stator wires have a “rubbery noodle” texture and flex response that is completely different from your ordinary under-the-cowl wires. I assume it is from age or degradation although everything was running fine like this for the past few years until a cou...

Thanks Butch. That’s what I gathered. I found an online manual for it and I think the (basic skimmer style) transducer draws 200W RMS, (peaks are higher of course). Definitely worth paying attention to, when you’re out all day on a one-battery boat, and don’t have a dedicated house battery that is s...

Great info, guys. Thank you. As you may have guessed by now, the boat in question is NOT a Boston Whaler boat. My Montauk (actually it's 1998 Alert 17) cannot go 55mph either. Nor can my 13 Sport. A couple more questions: The boat in question has only very rudimentary systems, only a tachometer, in ...

I have an old but almost never used Lowrance basic SONAR. Depth and water temperature were what I use it for. There is an input for a paddlewheel speed sensor, which I bought off eBay. Are paddlewheel speed sensors only for trolling speed? Or are they good up to 55-MPH? Race-grade precision not need...

That is a very great help, thank you. Who knew that Lowrance would keep such a list?

My 1998 classic Montauk (Alert 17) has (and came with) an old black-and-white large screen Lowrance SONAR. I'm away from my boat right now, so I can't say which model, but it uses the gray connectors that attach to the back, one for the transducer, one for the paddle wheel speed sensor. I am perfect...

Discovered something: The fuel pump on my motor was missing some internal parts: a spring with a disc on the end, to keep the diaphragm under tension. I discovered those things were missing, by looking at the manual... Which I had not done up to this point, because I hadn't really needed to. I had b...

My 1987 Mercury 1502-liter with oil system removed and using premix fuel runs strong and idles well. I love this engine, but: —if run at idle or low throttle long enough, the engine stops drawing fuel, empties the line, and dies. If I pump the bulb back up, it fires right up and runs great. —if run ...

As to not garner any undeserved kind treatment, I am an American. It just happens that I grew up here in Australia, so a lot of my acculturation including my taste in sports :cough:cricket:cough: has come from here.

Not to mention an 8 hour drive in Australia does not make for a broad cross section survey except for the part of Australia btween Melbourne and Sydney since there is an additional 148 hours of driving to see the complete coastline of Australia.

Given characteristics of large and sparse, the ability to (at least try) to fix-it-yourself is probably the most important aspect of running 1970-era engines in Australia. We all spend our disposable income on things that are indulgences. This is a plausible hypothesis. I cannot disagree. Of the ab...

I think you are equating buying a modern, computer-controlled, high-performance, low-emission, excellent fuel-economy, high-reliability outboard engine with being pretentious and sanctimonious. I think you are missing a subtlety. Based on my observations of two culturally similar locales, the econo...

I am [in] Australia right now to play a cricket tournament. Despite being the home of legendary ocean and surfing culture-- that was largely exported to and adopted by Southern California--Australia is utterly devoid of sanctimony and pretension.

Also, I don't understand how you could get power from the ignition key circuit when the battery master switch was in the OFF position. Something is odd about that wiring, too. Sorry if my description was confusing. There is no power anywhere on the boat if the battery master is in the OFF position....

1987 Mercury 150hp, two-stroke-cycle motor. Previously, I had the fuel gauge and sender system wired to the Perko battery master switch. So when I turned on the battery, the fuel gauge went live. At that point in time, I had nothing powered by the ignition switch except the ignition. That meant no t...

What happened to your Mercury 90 FourStroke? It's a Yamaha, too. Essentially a Yamaha F100.

I have one on my 1998 classic 17. It's heavy, but otherwise very nice. On a utility boat like a Whaler, I don't mind the bulk. I have other boats with lighter more powerful motors for speed.

I have owned FISHNFF/Brian's former Alert 17 since early 2011. It was center console when he sold it to me, and looks pretty factory.

When I travel abroad, I most often see Yamaha-brand outboard engines, but they are the fabulous, oil-injected, carburetor two-stroke Yamaha engines that used to be common here when they were introduced in the 1980's.

About 50-years from now, a c.1970 Evinrude two-stroke gasoline engine with a carburetor will still be running. I wonder how many c.2010 Evinrude E-TEC engines will still be running. This is not lost on third world fishermen, where feeding your family takes precedence over the vanity and luxury of l...

I have had 2 strokes the past 15 years plus, mine smoke at first start up but while running the rest of day, start and stop there is no noticeable smoke but they are louder all the time while running than an ETEC or 4 stroke and burn more fuel but they are easier and cheaper to maintain. All perfec...

pcrussell50

If you're getting significant smoke while under way you may have a mechanical problem that will need fixing. Much above about five knots you should see nothing but a thin wisp of smoke, by which point you also won't be breathing it. When on plane you should see none at all and for sure not breathing...

Even though Tony and I differed almost diametrically when it came to politics, and boy did we "joust" in these pages, it was all put aside in an instant when I wanted help finding a certain Whaler. He found one of the Whalers I now own, up in the bay area (I'm in SoCal) for sale, alerted m...

The weight difference is not just a matter of elegance (less weight for more power is always more elegant than the other way around), it also matters for us owners of classic Whalers, where the weights of today's engines were unheard of back when our boats were designed. A 400-lbs 90-HP engine on th...

$20,000 for a 50hp outboard is probably no big thing to folks who are ok with $300 hammers and $500 toilet seats... What I'm more curious about is what it will be used on?

pcrussell50

Another note about full throttle: I think modern outboards with jewelled bearing (and by that I mean from late 1960's onward) can be run at maximum RPM for as long as you like, provided they are in a proper state of repair. Of course that would be forsaking fuel economy.

Along with the outrageous claims, that's why I've begun to think that article is more of a low rent infomercial.

The motor was touted as big displacement for the HP when released. How would you then pump up the HP with the same displacement without contradicting yourself? Not sure if more cubes could be added to that particular block. It may have been touted as big displacement for the power. A dubious enough...

I have nothing to add to Jim's very complete answer except to add a data point by saying that I have the 150hp version of this engine and it already had the oil system removed when I bought it in 2014. It has been working very well with premixing oil into the gas.

If that c.1986 Mercury 150 has their 2.5-liter 60-degree V6 block, then you have a great classic outboard. Keep it running. My '87 150 is a 2.0L, 60 degree v-6. I'd bet the OP's'86 is, too.
