Lubrication questions For Old Gale 3 hp Please Help

[Dave Barnett]

I have a 1950 Speigel Brooklure 300 (3 hp). I have been told the Fuel mix ratio is 16:1 by one person and another has told me it is 28:1 Can anyone help me with the correct mix? Also my motor only has ONE grease port or screw in the lower unit. What type, weight of oil or grease should I use in this motor and how much should I put in? Do I just lay it on it's side and fill it full?? I don't want to blow any seals out. Also on the fuel mix again, The operation plate on the motor says to use SAE 30 oil in the gas. Would a good 2 cycle oil work as good or better?? Thanks for any and all help and advice. God Bless. Dave

I am pretty sure your 16:1. 24:1 came out in about 1957

2-cycle oil is made from SAE-30.

Thank you a bunch. Any ideas on the lower unit gear oil?

I think the gear case uses libriplate 105.

Confirming, lower unit uses outboard motor gear grease, no longer available. Most people use Lubriplate 105 "Motor Assembly Grease". NAPA Auto Parts sells it. Comes in a squeeze tube.

There IS a second lube hole, on opposite side from the big one you are looking at. It looks like a screw head. Squeeze the grease in the big one until it comes out the smaller one.

Modern TCW-3 outboard motor oil is far superior to the old SAE-30 oil. Mix it at 16:1.
