Maintaining Johnson/Evinrude 9.5 hp 2 cycle outboards 1964 – 1973   (Information & normal repairs)

The  9.5 hp, shown below was built from 1964 to 1973, which was a the first of the low profile motor series, and  is not a sleek looking motor in my opinion, with a squatty oversized motor cover & upper housing sitting on a standard lower unit.   Someone coined the phrase "Turtle Motors" for these squatty motors. 

There are a lot of similarities between this motor & the earlier motors from 6 to 10 hp but with the powerhead setting lower & a shroud around the mid-section.   

I understand it was also basically a souped up 7.5 hp powerhead.  Some experienced mechanics say the crankshaft did not stand up under heavy usage as a 9.5.   But then in the early years of these motors was before the TWC outboard oil came into being, so that use of automotive oil could have also have been a contributing factor.   They also say that changing the water pump impeller is not as easy as the others because the water supply tube to the powerhead will many times come undone at the powerhead & it is a problem getting it back in place.

The carburetor is placed on the rear starboard side of the block.

The manual recoil starter pull handle is located on the front lower part of the  front panel.

Most of these motors you will see are short shafts, however they did make a longshaft.  From what I can tell probably just a longshaft 5" extension off an earlier QD motor of the same basic size was used.   The lower unit was not unitized like the later 9.9's,  & it appears that they actually use the lower unit (gearbox) off the earlier QD series.

It apparently was not originally designed for remote controls, however I have seen an aftermarket version & the one shown below did appear later on OMC literature for accessories.  This is evidenced by the taller shifting lever on the motor in the photos below.
