Well, this lifetime Johnnyrude owner has gone and bought a Mercury! I know nothing about Mercs but couldn't pass up this deal. It is on a 1961 Starcraft Arrow, and it is in awesome condition. I posted a few pics, but there are more posted in the Boat Forum.
Anyway, the seller said:
1. In the lower unit, you use grease, not gear oil. Is that correct?
Looks like a standard drain/fill plug at the bottom of the L/U. At the top, I see a "flush" plug about the size of the vent/overflow plug on a Johnnyrude, and a smaller screw next to it, and a little lower. Which is the vent/overflow for the gearcase?
2. Run 32:1 gas
il ratio. Is that correct?
I have't been able to figure out how to remove the cowl. I see a thubscrew type bolt at the bottom of the front cowl cover. Almost looks like a carb adjustment knob, so I haven't monkeyed with it. Does that come out to remove the cowl?
Also, there is a knob on the top front of the cowl, on the starboard side which pulls straight up. Is that the manual choke?
Needless to say, I'm getting a service manual, but just wanted to get some ideas.
I think the carb may need cleaning/adjusting as the motor started right up and ran great for a few minutes. Then it started bogging down. By returning to a slow troll and then going to WOT, it resumed good speed and didn't seem to bog down again during the test run. At WOT, the tach was reading 5000rpm. Is that about right?
Thanks for any help!
