Test Running a 35hp motor for a customer with remote set up on a 13' early 80's Boston Whaler.  We hit 32MPH easily.  Featured is optional Panther Power Trim which makes a big difference in performance!  Great motors with nice idles and enough power to get you up on plane when loaded.

32 cubic inch 20-35HP motors (1977-2006) rival the popularity of the 9.9/15hp motors produced over 3 decades.  Big brothers to their smaller counterparts, they are widely recognized as bulletproof workhorses.  The design of these motors (particularly the block internals) remained fairly similar over their 3 decades of production.  Commonly used on Boston Whalers, work barges, & skiffs, they offer power with simplicity & ruggedness of components.  All models are detuned 35hp blocks.  The 20, 25, & 28 hp motors are very similar with significant changes to the carburetor and manifold prior to 1986.  The 30 & 35hp motors are the same with changes to the block porting, depending on production year.

20-35 hp
1977-06 manual


Here is a video of an '87 50hp short shaft Johnson on a 17' Brockway Skiff (wood boat) using a 12.5 x 15 prop.  RPMs hit 6,000RPM (top end) at WOT with 2 passengers. We hit 30MPH.  2 pitch higher and we would have broken 35MPH.  The motor threw us back in our seats when I dropped the hammer.

40-50hp motors follow the same approach of their smaller counterparts; the 40, 48, & 50 are essentially the same motor.  50 & 48 motors are identical, the 48hp denotation was a marketing ploy to sell 50hp motors without oil injection or power trim at a lower cost, but the same HP output is seen by both. The 40hp motor is a detuned 50hp to create lower power output.  The added feature of these motors is that power tilt/trim is available and the power output affords application to larger vessels and heavier pontoons. These motors are also loopers in design; the are much more fuel-economic then conventional cross-flow motors (same original mechanical design as the first outboards produced in the late 1890's).  Many of these motor were produced as they still fell into the "common mans" price range.

40-60 hp
1980-06 manual


Here is a 1992 70hp on a 19' aluminum with heavy flooring and a heavy center console build out.  We hit approx. 30MPH.  Customer opted to have a 15hp Johnson kicker motor installed for slow speed trolling too.

60-70hp motors follow the same approach of their smaller counterparts; the 60 & 70 are essentially the same motor.  The 60hp motor is a detuned 70hp to create lower power output.  Power tilt/trim is available and the power output affords application to larger vessels and heavier pontoons. These motors are loop charged for improved fuel economy.  Moving into this motor class still affords a relatively light motor (approx 250lbs), but produces enough power to move 15-19 foot vessels at comfortable speeds (25-40mph).

60-70hp
1980-06 manual


This 90hp Ocean Runner pushed the 20' fiberglass skiff along nicely at around 30mph in the fully lowered trim position.  Trimming up gave another 300 RPM and 3 MPH.

V4 motors began production in the late 1950's and were produced through 2006. As production evolved, they maxed out at 140hp. They were produced as both traditional cross-flow motors, and loop-charged for improved fuel economy. These work horses provide power for larger boats and depending on hull design, can be found on vessels as large as 23'.

Just like smaller OMC motors, the larger blocks were detuned to lower output motors. The 88, 90, 100, and 115hp motors are all from the same 'family.' The 120 & 140hp motors are the same with modifications to change power output.

V4
1980-06 manual



This 150hp 60 looper pushed the 19' boat along at 44MPH with a 19 pitch prop, turning 5200 RPM. 

V6 motors began production in the mid 1970's by OMC.  As with all the smaller motors, OMC incorporated their innovations and designs to make these motors perform just as well.  V6's started as crossflow motors but eventually were produced as both loopers and cross flow with a 90 piston and crank configuration.  In the late 1980's the block was redesigned to be 60 and include other features such as an integrated vapor separator.

These motors are widely recognized for having a tremendous amount of torque for getting large vessels up on plane and being work horses.  They are very similar to V4's but simply have larger blocks.  V6's can push boats as large as 28' long when installed and operated properly.

Just like smaller OMC motors, the larger blocks were detuned to lower output motors. The 150, 175 motors are 60 engines, the 200 and 225hp motors are 90 loopers.  There are various speciality versions of these motors such as the Venom and Intruder with special machining to give greater power than what the stickers stated.  These were usually used by tournament operators; today's motors say H.O., or High Output to indicate the special tuning.
