    When did they stop using the 470 mercruiser engine?

    I see they started in 1976 and have seen posts with people with 1989 year boats with it. What year did they stop using the 470 or are they still using it in some form or another in boats?

    Replacing my bellows - Shift cable question?

    I'm replacing the bellows on my 1989 Mercruiser alpha 1 and when I did this 3-4 years ago, I had to replace the shift cable at the same time. Fast forward to yesterday when I'm removing the outdrive and other parts to do the bellows again due to cracks and after taking the shift cable out, I...

    prestolite tilt pump rebuild question with pics!

    My boat is a 1972 tri hull with a 72 evinrude electric shift. Motor runs great, boat is good also, however, the tilt has always leaked down and doesn't work correctly. I took the pump apart last winter and have finally cleaned it up and am ready to put it back together, but i cant remember...

    idle issue fixed, now tach just stopped working

    Got my boat to idle approximately at 750 rpm and its smooth. It was the little screw on the carb linkage that was too far out. Just a small adjustment and it made a huge difference. I then turned the boat off, waited a few seconds, and turned it back on and the tach no longer moves. What...

    engine still running rough, wont idle. 73 evinrude 50 hp electric shift

    I originally took this video to come on here and ask about the exhaust gases coming up through the hole, but I found another post where a guy said to just inject silicone sealer to encase the wires and let it cure to seal off this hole. I didn't have a rubber grommet and didn't know to do this...

    72 50 hp evinrude, key doesn't stop boat

    Found out something else interesting while troubleshooting my boat issue. When you turn off the key, the motor keeps running. Where should I look first? Could this be related to the poor performance, hard starting, and rough idle I'm experiencing? Both spark plugs show spark with a spark...

    1972 50 hp surges

    Motor is hard to start, appears to be sparking on both cylinders though using a spark plug checker. Compression is 150/155, I have done the link and sync, but the motor just wont idle. I tried to set this though with the remote control attached and I think I need to disengage that and set it...

    switched wires on 72 electric shift

    Hypothetically, if I had my two wires coming from the powerhead hooked up to the solenoid wires in the reverse, what would be the outcome? Neutral button pressed = ? Forward button pressed = ? Revese button pressed = ? I'm not thinking well enough today to figure this out on my own. I'm...

    1972 OMC Tilt keeps leaking down

    I have a 1973 OMC tilt that feels like it needs bled, but doesnt. I had the entire thing apart today and the two seals on the shaft looked and felt good. There is one O ring seal and another that both looked in great shape. I'm at a loss as to why it has a slow leakdown, but it doesn't leak...

    1973 evinrude 50 fuel pump routing

    I have a fuel pump with 3 nipples. The one on top, the filter nipple, rotates and goes to the fuel inlet I believe. There are two other nipples, one an outlet to the carbs I imagine, and one to the pulse nipple on the boat. The intake manifold has two nipples, a large one and a small one. I...

    1973 electric shift 50 horse. Need picture of throttle cable on motor side

    I'm finally getting around to replacing the powerhead on this old evinrude electric shift beast and I don't have a clue how the new throttle cable goes. I know the end with the adjustment wheel goes on the motor side, but I don't see where it anchors down to where I could use the wheel to...

    pick between these two classics

    I have an 89 regal and its a great family boat, but too big to fish out of with my 2 boys, 7 and 9, and so i want to get a fishing/sport boat or something thats cheap that will function as one with an outboard. I have come across these two boats. I have not posted them with the image tag...

    Dirty bottom

    How much grit does it really take on the bottom of a boat before decreased speed is really noticed? I've seen boats that aren't completely smooth on the bottom to ones that feel like 40 grit sandpaper (to worse!), but wonder, how much growth is acceptable before it really impacts boat...

    stuck at 3k rpm (merc 3.0)

    I'm at a loss. I've rebuilt my carb and it idles perfectly, gone through a couple tanks of fuel, rechecked the carb, changed my fuel filter down by the oil filter, cleaned my points, set my dwell and timing, and still, I'm stuck at 3k rpm and about 30 mph on this 1989 Regal Medallion boat...

    Trim pump reservoir failed

    Yes, I thought it was leaking since the day I got the boat, but after taking it out, its definitely the source of the oily residue in my bilge. I have heard that these older style, single bolt reservoirs will eventually spiderweb and crack at the bolt hole, especially when overtightened...

    185 Medallion cleat needed

    I'm missing a cleat for my 1989 185 medallion.. its one of the cleats on the side towards the rear. I can't seem to find any that are identical to what I need and don't want to use one that doesn't match up. Where can I get these?

    89 Regal, 3.0 liter mercruiser, low rpm at wot

    At WOT in our boat, the tach only reads a hair under 3000 rpm with this 19 degree 3 blade prop, and dead on at 3k with the 17 degree 3 blade prop, both aluminum. If I wasn't firing on all cylinders, would 3k rpm be about the norm? I can never start it up and have it idle without first...

    rescued a boater in distress today

    We put in for the 3rd time ever today on Clinton Lake in Lawrence. We started cruising out to the middle of the lake and saw up ahead of us a lady waving her arms. We made a detour over to the boat in question, a 24 foot pontoon, and saw that their transom had rotted through and their outboard...

    Its all about the almighty dollar

    One thing I wanted to get off my chest and then I won't talk about it again is how expensive dealers, mechanics, and even internet sites make boating out to be. It doesn't have to be that way. Regarding alignment tools, get one for piece of mind, but there are cheaper ways of making one if you...
