Outboard motor height diagram

1. Use transom drilling fixture (91-98234A2) or attach (tape) engine mounting template (located in this manual) to boat transom. 2. Mark and drill four 17/32 in. (13.5mm) mounting holes. 3. Refer to "Determining Recommended Outboard Motor Mounting Height", preceding, and install outboard to the nearest recommended mounting height. 4. Boats with extended transoms, brackets that extend the mounting bracket for the outboard motor behind the back of the boat, can use a higher outboard height. The brackets can add 1 inch to the overall mounting height of the outboard. The standard shaft length for most outboard engines less than 125 horsepower is 20 inches. Sometimes high-strength sealants also cause height fluctuation for a mounted outboard. The outboards have mounting holes that are vertically aligned. After attachment, the outboard may look like it's dangling. This suggests problematic adjustment. The comparative size of the gear case for a new engine may require a change of height.

A long shaft engine requires a height of 20″ and extra-long shaft engines will need a transom height of 25″. While this is the case there is certain saltwater motors that are extra extra long at 30″ and 35″ shaft. Keep these numbers in mind if you ever have a need for a new outboard motor for your boat. If motors are at the transom,the cavplates should be just about even or a little higher then the bottom of the transom. You are setting back about 2' or more,so ... This transom height should match your outboard motor's shaft length, which is measured from the bottom of the engine head to the anti-ventilation plate. I recommend adding up to 2 inches to the outboard motor shaft length to be on the safe side (see height diagram). So, for example, if your small fishing boat has a height of 15 inches in the ...

It's easy to tell if your engine height is right: with normal load (50% gas) ,get someone to take it up to cruise, trim it normal, and go back and look at the big anti vent plate above the prop on the lower end. It should be OUT of the water at speed, getting splashed is ok, but out of the flow. Here's how to make sure that your outboard is at the correct height by using your anti-cavitation plate as a guide: · Find a straight edge that is around 8′ to ...

Boost Speed with Outboard Engine Height Adjustments. Raising an outboard higher on the transom can reduce drag and raise top speed. Any owner seeking the last bit of speed from an outboard-powered boat should grab a yard stick. Not to measure boat speed, but to gauge the mounting height of the outboard motor on the boat transom. An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom.They are the most common motorised method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and ... Oct 3, 2019 — A dealer might guess at the optimum outboard motor mounting height by aligning the anti-ventilation plate slightly above or at the same ... guess at the time was that the engine was mounted about 1/ 4-inch too high. When the water had a light chop, the hull bounced just enough to ingest high levels of air into the in-take foot. With the outboard already bolted to the transom, the best option was installing a transom jack. Placing the motor just 1/ 4-inch to / 2-inch above the opti-

The easiest way with Yamaha Outboard Motor's due to the fact that model records have changed over the years, which makes older outboard motors to be difficult to properly identify. However, this technical article illustrates the difference between the serial number and model as well as showing the location where you can find these.

Re: Motor height on pontoon? Just mount the motor full down. A 50 HP motor on a 20 foot toon is going to want all the bite it can get. In fact unless you have a bunch of power (say 100 hp or more) mounting full down is the best setup. The engine on a pontoon operates in very turbulent water so the lower you get it into the water the better.

Any owner seeking the last bit of speed from an outboard-powered boat should grab a yard stick. Not to measure boat speed, but to gauge the mounting height of the outboard motor on the boat transom. Rest the yard stick or another suitable straight edge along the keel on the bottom of the boat so that it makes a straight line aft to the outboard. With the motor trimmed so that the propshaft is ...

A special case is an outboard on a bracket. At speed, the prop runs in a hump behind the hull and the bracketed outboard can have its cavitation plate 2" higher than the bottom of the boat. The bracket manufacturer will recommend the outboard height according to the bracket shape and length. As a yacht designer and boater, I prefer longer shafts.

How you get the motor to that height is another discussion. An electro/hydraulic jack plate adjusts the motor height with a switch and can be done while underway.

Sometimes high-strength sealants also cause height fluctuation for a mounted outboard. The outboards have mounting holes that are vertically aligned. After attachment, the outboard may look like it's dangling. This suggests problematic adjustment. The comparative size of the gear case for a new engine may require a change of height.

Boats with extended transoms, brackets that extend the mounting bracket for the outboard motor behind the back of the boat, can use a higher outboard height.
