Mercury MERCRUISER, Service Manual, Page: 146 / 566

7. Divide the remaining weight to be placed onto the boat by the MerCruiser person weight to get the maximum number of
passengers to load onto the boat.
• 985 lb ÷ 165 lb = 5.9 passengers
• 5.90 passengers rounded up = 6 passengers
8. Using the totals in this example load 56 lb cargo in the aft storage, 113 lb cargo in the center storage, and 56 lb cargo in
the bow storage onto the boat before adding passenger weight. Then, load six 165 lb passengers, onto the boat with 500 lb
on the swim platform.
• 500 lb + 225 lb = 725 lb
• 725 lb + 165 lb = 890 lb
• 890 lb + 165 lb = 1055 lb
• 1055 lb + 165 lb = 1220 lb
• 1220 lb + 165 lb = 1385 lb
• 1385 lb + 165 lb = 1550 lb
• 1550 lb + 165 lb = 1715 lb

Clear Hose Measurement Method
1. Obtain an 8–10 mm (5/16–3/8 in.) ID (inner diameter) clear hose approximately 4.5 m (15 ft) long. Install a metal fitting or a
weight on one end of the hose to keep that end of the hose below the waterline. The fitting or weight must not restrict water
from filling the clear hose.

b - Fitting
c - Unrestricted opening
IMPORTANT: On engines equipped with more than one exhaust elbow, perform the exhaust elbow waterline height
measurement on the side that sits lower in the water.
2. Put the weighted end of the clear hose over the side of the boat (port or starboard) that is sitting lower in the water.
3. Submerge the clear hose until completely filled with water.
