Mariner bogging down

[raypack]

Motor bogs down somewhat when planing out and bogs down/shuts down when loading on trailer. 1987 model 175 HP on Ranger 370V w/ 29 pitch prop. Any suggestions on how to fix?

when were the carbs last cleaned? any blockage in the fuel tank? do you have an in-line fuel filter? When were the plugs changed last? Could be a whole host of things without more info

Whenever a 2 stroke is not performing you start with a ----Compression test------It is the absolute first thing to do on a 2 stroke outboard.-----------------They work hard and are often subject to broken rings / piston scoring.
