They usually don't stay round/true after heating
Kevin is right, it is for sleeve alignment. There is a bolt that goes in that hole when you remove the plug. The bolt is turned to a pencil point very much like the bolt that goes in the shift linkage that attaches the shift rod from the gearcase to linkage on the bottom of the powerhead on a factory engine. If my memory serves me correctly it is a 1/4-20 bolt. The sleeves are slotted at the bottom in two different spots so it will align a port or starboard sleeve.
Love it!!
Thanks Freddie and Al!
Attachment 330906Here is the motor on a 16' tunnel. I know speed master type gearcases don't leave hard but this one did ok.
Motor was maybe a little large for the boat.
Freddie that's fantastic!
My son Gavin that's Attachment 330909seventeen now. Time gets away Gavin was 4 or 5 in that picture.
Those sleeves are really thick and stay pretty round when sleeving. I also never cooled the sleeve just heat the block and they drop in.
