Troubleshooting
Hydrolock
When an engine has been hydrolocked from water or fuel it is important to find the cause and inspect all compo
nents which may have been damaged. Be sure to check the items on this list to ensure maximum service life
from the engine. If fuel hydrolocked, check carburetor fuel inlet needle and seat condition.
Find the cause of excess water in the hull. (i.e. Was the craft submerged? Righted improperly after being cap
sized? Is the bilge siphon system functioning properly? Does the cooling system have a leak inside the craft?
Is the hull leaking, allowing water into the engine compartment? Are seat or compartment seals in place and fitting
tightly? [jet pump O-ring, driveshaft through hull fitting, speedometer pitot fitting, steering cable seal, air/water
separator drain line, bilge siphon fittings through hull, cooling water supply through hull, etc.]. Was the engine
left running when the craft capsized?)
• Engine Compression - verify within specifications (See Engine Section)
• Reeds - inspect for damage (See Carburetion Section)
• Fuel Tank/Venting - check fuel tank and vent system for water
• Crankshaft Indexing - verify crankshaft has not been forced out of index (See Engine Section)
• Flywheel and Key - Inspect flywheel, key, and keyways for damage. Check ignition timing marks
on flywheel with a dial indicator before the engine is disassembled to verify proper positioning.
(See Electrical Section)
• Fuel Pump - check diaphragm condition (stretched from water pressure)
• Cylinder Condition - check base mounting flange area for cracks
• Check Applicable Service and Information Bulletins
If damage is suspected and engine is disassembled, or if water was left in the engine:
• Bearings - inspect all bearings for rust or damage
• Connecting Rods - inspect for damage, inspect small end carefully for dents, pitting in bearing
surface
• Piston and Piston Pin - Inspect for cracks or damage
