choke and propeller

[kathymwae]

i have just purchased a used boat with a 50hp force, 1985 motor. it runs fine, but to start the motor for the first time in the morning i have to spray starting fluid on the carburator. after that it starts fine all day long. is there a simple solution to fixing this problem. i don't mind except it's a pain to remove and replace the motor cover every day.
2ndly. how do i know i have the right pro on the motor. is there a simple way to determine this. i have read a little on line but it all sounds so complicated. pitch etc. what prop normallyu comes on the motor and is usage a determination for prop size. i fish, and i pull tubers, and i just take a ride and jump small waves, if that helps to get an answer.

Re: choke and propeller

are you making sure that the primer bulb on the fuel line is pumped up firm before attempting to start?.

proper prop should allow you to reach max rpm's at wide open throttle

Re: choke and propeller

starting fluid is not good for a 2 stroke it might be a dry type start .. anyway is the choke working and yes check the primer bulb also like stated above also the other post is right on the prop reply

Open fuel tank vent

Check the kill switch, place in "run" position

Squeeze fuel primer bulb till firm.

Advance the throttle 3/4 way, without putting it in gear. -- This is done by either pushing a button in the center of the controls, or pulling the shift handle toward the driver, or raising the fast idle lever, all depending on what control unit you have.

Activate the choke (fuel enrichment valve) by pushing in on the key. The valve is only open while the key is being pushed in.

Turn the key to start while continuing to hold the key in.

Release the key and choke when it starts.

3-5 seconds of "choke", is usually enough.

Be ready to pull the throttle back toward the idle/neutral position, when the engine starts and the revs increase.

Continue to pull the throttle back as the engine warms up.

You should not have to use the choke much, if at all, once the engine has warmed up.

Engine should start within 10 seconds of turning the key.

THE RIGHT PROP --- is dependent on the boat and the load.
You want a prop that lets you reach the maximum rpm for your motor.

So you need to know your wide open throttle (WOT) rpm, and the diameter and pitch of the prop you currently run.
