The following is described in the outboard does not meet specifications. It is a first step to decide if a tune-up is all that is
required verses a major overhaul of the Raider.
1. Visually inspect engine for leaks, missing or loose parts, or other obvious defects.
2. Compression check Compression check Compression check Compression check - Proper compression is essential for good engine performance. An engine with uneven
compression cannot be properly tuned.
•
Operate the engine until it reaches its normal operating temperature. Stop engine.
•
Remove and inspect all spark plugs. Check their condition.
•
Install thread-type compression tester in spark plug hole.
•
With throttle in wide-open position, pull engine through at least four compression strokes.
Variation between cylinders should not exceed 15 PSI (103 kPa).

IF IF IF IF the engine has equal compression, is hard to start, and and and and operates poorly, check for:
•
scored cylinder walls
•
damaged pistons
•
stuck piston rings
•
worn piston rings
IF IF IF IF the engine shows a variation greater than 15 PSI (103 kPa), check for :
