Make sure you have plenty of impeller replacement kits, you'll need them! So many steps gets to get the engine trim down people are not going to remember. The engine will continually be started out of the water. You'll be better off just leaving the engine down.
On a Merry Fisher 725 with 4 Persons and approx 60 litres of fuel, plus extra equipment on board and a 19 inch stainless prop, that boat type will cruise at approx. 8.5kts at 3000rpm, and around 19kts at 4400rpm at around 38 lit/hr. 2800RPM will reduce engine wear and fuel consumption with little effect on SOG. Idle tickover is 600-650rpm at around 1.4lit/hr when 'warm'. A poor engine setting would be between 3000 and 4100rpm, with higher engine load and fuel burn producing only in the region of 12-15kts (not planing, in a bow-high 'semi-displacement' type attitude. RPM above 48/4900 the speed increases but relative efficiency begins to drop. 0.5-0.7 litres per nautical mile is likely to produce optimal / efficient cruising speed and attitude / engine load factor with this engine and hull type / vessel mass, depending on sea-state, trim configuration, overall onboard mass and other factors. These Suzuki engines have been directly observed to have very high-reliability and performance consistency with no mechanical or electronic failures or issues observed through many thousands of hours of operations using the DF30, DF50, DF90 and DF150 and DF150AP variants. The newer DF-B variants have recently been confirmed (directly by a Suzuki-approved and trained engineer) to be the same engine but in a slightly different form factor / updated-looking controls.
Hi, you have a 22 foot boat weighing 4079 lbs but the motor is only a 150 hp. Is that enough hp to power your boat? Have you experienced any issues getting on plane, especially when the sea is rough?
Hi, thanks for the comment. No such issues have been observed with any difficulty achieving planing speeds or with lower than expected or even 'sluggish' acceleration.

Thank you so much! Finally someone who explained how the key fob actually works. The Suzuki manual isn't very specific...
Thanks this realy helped
Don't worry about the instrument covers, they'll be lost soon.

I too would like to know how the boat goes with the 150hp Suzuki please. Ease of planing and top speed.
