BOAT OPERATION

Engine Inspection

Remember your "WOBBS" every morning. (Water (Coolant), Oil, Bilges (Inspect and
Pump-out), Belts, and Sea Strainer. Check the level of COOLANT in the expansion
tank. Check the level of your engine oil with the dipstick. DO NOT OVERFILL! Fill
only if oil level is below the ½ mark. Check the general condition of the hoses and
belts.
Ensure the RAW WATER THRU-HULL is OPEN! (Lever in-line with valve). Check the
sea strainer for debris. If necessary, close the thru-hull, open the strainer lid, clean
. REOPEN
out debris, and reassemble the Thru-hull!
Start Up
Maggie has a 40 hp Yanmar engine with a 3 bladed prop. There is an ignition,
throttle and transmission control in the cockpit. The vessel cruises at 2400 rpms to
a speed of 7 knots; running your engine much above that will burn a lot more diesel
at the gain of very little boat speed.
The boat has a definite prop walk to port in reverse with not too much noticeable
effect in forward. When in reverse, be careful to keep a firm grip on the wheel. Use
only low RPMs in reverse.
To start engine, set the battery selector switch to the number 1 position. Place
transmission in the neutral position (usually straight up). If the engine is cold, first
preheat it by turning key in preheat position for about 15 seconds. Your oil and
temperature alarm will sound. Push the starter button (or turn the key all the way
over). After the engine starts, warm it up for about 5 minutes at about 1000 rpms.
Check the transom for water and exhaust as an indication that your thru-hull is open
and water is keeping your engine cool.
Do not hold the start button for more than 15 seconds at a time. If the engine does
not catch the first time, wait about 15 seconds before trying again.
After the engine starts, warm it up at about 1000 rpms for about 5 minutes.
Observe your gauge readings. Oil pressure reads around 50 psi and water temp
around 180 degrees. Engine temperature should rise very slowly.
Note: If water temp.is high or oil pressure low, shut down engine and look for
problems. Was there a lack of water exiting with exhaust? Are thru-hulls open and
debris cleared from sea-strainer? If problem keeps occurring, call SHYC Service.
Shut Down
Before shutting down, let engine idle for about 5 minutes to cool. Ensure the
gearshift is in the neutral position and the throttle is in idle. Turn off the engine with
the key.
