What is my antique outboard motor worth - described in detail with questions

[rsabola]

Need some info if anyone has any experience with this outboard.

Starling P-500 Jet Drive made by Propulsion Research, Inc. in Minneapolis within the 1965-1968 time period. The 5-hp, air-cooled, single cylinder 2-stroke power head was built by Clinton Engines Corporation of Maquoketa, Iowa. Weighs 29 pounds, stands 34" tall. It is squeeky clean because I just finished the cosmetic restoration.

Anyone know what this outboard is worth?
Also, Anyone know what is the best oil to use in this outboard?
I heard a TCW-3 motor oil at a ration of 4 oz. per gallon is best. Is there a better one because it is air cooled?Just wondering in people can give me some information. Thanks.

Howdy, R Sabola.

Welcome to iboats.

$142.17, or whatever someone will pay.

Use chainsaw oil. You could also use the Pennzoil synthetic TC-W3 at the same ratio. The 4oz is okay (32:1)

Since the egine is air cooled, would a 32:1 ratio 2 cycle chainsaw oil be the best for the engine? What kind of chainsaw oil is best for this - Stihl?

I have a container of TCW3 rated oil;to not be long winded the label lists 2 stroke motors from lawnmowers to snowmobiles.Also in my 7 aftermarket outboard repair manuals all air cooled 2 stroke outboards say use a good quality outboard lube.

Re: What is my antique outboard motor worth - described in detail with questions

I use Stihl or Husky oil in all my 2 stroke air cooled motors. The difference in TCW3 and chainsaw oil is the amount of ash that is used as a lubricant. Air cooled motors run hotter and in chainsaws and weedeaters they run at a higher rpm. Water cooled outboards don't get hot enough to burn off the ash and they will load up after awhile. The advent of synthetics may have nullified this whole argument but I still stick with TCW3 in my water cooled outboards and chainsaw oil for the aircooled motors. As to value it is what others have said ...."whatever someone will pay". By and large the reason people buy old outboards is the value and the enjoyment of fixing them up, their worth is almost entirely intrinsic.
