Re: evinrude....what its HP and YR?
Model: 15034<br />Make: Evinrude<br />Year: 1961<br />HP: 18<br />WOT RPMS: 4500<br />Displacement: 22.0 cu.in. = 360.5 ccm<br />Fuel to Oil mix: 24:1 Originally.
Read more here. <br />Sparkplug: Champion J4J (now J4C) gapped at 0.030. Use J6C if your fouling.<br /><br />That button is the kill switch. It connects those wires together when it's pressed, which kills the spark.<br /><br />Best luck finding a tiller:
Twin City Outboard <br />Failing that, try to locate an outboard junkyard.<br /><br />EDIT: It may not be a longshaft. If there's a removable section between the lower unit and the midsection, then it is. <br />Some of these older OMCs measure around 18" between the bracket and antiventilation plate, since the lower unit has to be submerged further for the waterpump to work.<br /><br />Good luck!
