41 Outboard Motor Height Diagram Diagram For You Thankfully, adjusting the outboard motor height can be easily done by simply switching the mounting holes. usually, the outboard motor features a clamp bracket that allows you to adjust the outboard motor height to a higher level than standard. there are a series of four to six holes with a spacing of 0.75”. A change of less than an inch in engine height made a big difference. by setting the engines one hole lower we noticed: a speed increase at low and medium rpm. at 3500 rpm we recorded a boost of 4 knots and at 4000 rpm we saw an additional 5.5 knots. slip numbers were reduced by 50% at 3500 rpm and by 70% at 4000 rpm.
41 Outboard Motor Height Diagram Diagram For You The perfect mounting height will depend on a few factors, such as the size and weight of your boat, the style of your motor, and the type of water you’ll be boating in. that being said, there are a few general guidelines that can help you determine the right height for your outboard motor. generally speaking, you’ll want to mount the motor. The problem is that none of those symptoms are by themselves precise indicators. we need a little more detail to better find the right outboard height. how to know if your outboard is mounted too low – a detailed guide. outboard height is tricky, mostly because every hull is different and the same is true of every individual outboard. The spacing between the upper holes is 0.75 inch. this adjustment is provided to let the boat builder or owner fine tune the mounting height. the clamp bracket on the latest mercury four stoke model outboards has five mounting bolt holes spaced .75 inches apart. in some cases boat performance can be improved by mounting the outboard at a higher.
