    Mercury 200 optimax what to expect?

    Gee, the Optimax is low emissions, because the scavenging is done with air only, not air+fuel, like in the carb engines. This should result in very low fuel an oil consumption, in comparison to the carb motor. Also, A lot of Optimax's could run on standard TC-WIII oil. You might check it.

    Mercury 200 optimax what to expect?

    In theory, the performance should be about the same, and plenty for a 17 footer. I expect fuel usage will be quite a bit less on the optimax. I am interested in this topic, as my neighbor had a 150HPV6 Optimax, and I thought it slow, compared to my Johnny 150HPV6 2 stroke carb motor. The...

    Mid 90s (‘95)Four Winns vs mid 90s(‘96) Monterey bow riders

    Four Winns usually had V-P outdrives. Are they still supported? Not sure what Monterey had for power.

    2003 Johnson J90PLSTC Starting issues

    Gee, "Dangit" doesn't cover that issue, IMO. "Rats" is necessary. A hole in the piston is bad. I would think the block needs to be inspected to see if there is any other damage.

    is a 60hp outboard too small for this boat

    Gee, I would try it. My rule of thumb is it the boat makes 35MPH, you are good. I think that 65HP motor will not do that, however. A guess would be a 90HP or greater motor to get 35MPH. JMO

    Can someone please help me to identify what year this is there in no tag with the ser # and it has a reman power head so there's no # on the block of

    Once you find out the year of the powerhead, you can determine if the airbox is correct, and if the airbox is correct for the clamshell cowling. Choke plates were d/c in newer models, The orginal V6 motors cane out in 1978, with choke plates. Not sure when they went the way of the Dodo.

    1981 Merc 115 i6 issues

    You cannot adjust idle mixture on a flusher device. It must be done in the water, in gear with motor warm. Initial mixture setting is 1-1/2 turn open from seated. Run motor in water, in gear and warm it up. Now adjust mixture screws 1/8 turn open, to allow acceleration, one screw at a time...

    2003 Johnson J90PLSTC Starting issues

    When the engine fires, the bendix is supposed to disengage. The bendix is doing what it is supposed to do. The issue is why the engine is not starting when that happens. Usually it is a issue where the motor is out of tune. Make sure the primer bulb is hard, and hold the choke closed and...

    Can someone please help me to identify what year this is there in no tag with the ser # and it has a reman power head so there's no # on the block of

    A '93 has a 1 piece cowling, not the clamshell that this one has. A picture of the carbs will let us know if they are wmv or wmk. I think the wmv were used on early models, and didn't have idle mixture adjustments. Later models had adjustable idle mixtures.

    Project Boat

    You will want a V8 in that 23 footer or a V6 in the 21 footer. They will be dogs with smaller I/O motors. An outboard powered boat of those sizes will have lots more room in the cockpit since they have no dog house. MerCruisers of those years need a lot of maintenance. Stuff just wears out...

    Can someone please help me to identify what year this is there in no tag with the ser # and it has a reman power head so there's no # on the block of

    Obviously a Merc V6. Since it has the clamshell cowling, that makes it late 80s or earlier. Most common were 150HP, but there were 135HP and 175HP motors in V6 as well. Merc changed from a single 40A voltage regulator to twin 20A VRs. What do you have? Carbs may have a WMK or WMV number...

    1991 Yamaha VX76 250hp Carbed model

    I doubt a 1991 motor has a computer. Check to see that the carbs open and the spark advances. Both are usually manual linkages.

    1986 35Hp Mercury no fire

    Gee, not many shops will work on a motor that old. If you plan to keep her, you will need the entire service manual. You will want to do a link and synch, as well as carb cleaning, rebuilding and adjustment. There is probably a spec on alternator output when cranking at a certain speed. It...

    Boggs down

    So you said that it revs freely in neutral, but bogs in gear on the flusher? If so, that is unusual as the flusher unlike running in a barrel, provides no load on the engine. Perhaps there is a load in the gearcase, like a bad propshaft bearing? Just a SWAG.

    1986 35Hp Mercury no fire

    The CDI Electronics web site used to have a troubleshooting guide for your motor. There is also a lot of info on the web, some of it is even accurate. You could buy a service manual. It could be a bad stator, bad trigger or bad switchbox or wiring. The wiring harnesses of motors that old are...

    1973 Mercury 850 Won’t Idle

    Set the idle mixtures using fresh-mixed 50::1 fuel. Make sure the idle pickup timing is 4-6* BTDC. The brass collar on the midsection of the distributor rotates to allow the idle pickup adjustment. I like to use 21*BTDC for max spark advance, with today's lousy fuel. Initial carb setting is...

    Bottom paint on Aluminum Crestliner

    One of the antifouling paints for aluminum hulls is Trilux. Reading the label makes me think the barrier paint coating is extremely important to protect the hull from the A-F paint. I would follow the directions exactly.

    Will vehicle work?

    Gee, I disagree with Horigan. You have 1000# excess capacity, plus vehicles are underrated a bit. You will also never add 1000# in fluids and fuel to that 'toon. I would worry about traction on the ramp. If the ramp is clean and dry, you should not have an issue. Sometimes high tide gives...

    98 Johnson leaking hydraulic fluid.

    I did not think they made crossflow motors in 1998. I thought only 60* and 90* loopers were made then.

    98 Johnson leaking hydraulic fluid.

    Your transom bracket looks a bit different than my '98 Johnny 60* 150HPV6. Maybe you have the 90* motor? I have a cradle between the swivel bracket and the transom bracket that swings down to lock the motor partially up. It can be swung into place from either side. Perhaps it is a trailering...
