"I just bought a 16 foot Grumm

"I just bought a 16 foot Grumman with a 1991 75hp Mariner, I always had small motors and I am new to starting a big motor, what is the starting procedure for this motor.

What are the max rpms that this motor, I am using a 13 by 19 in prop, and if my tack is correct I am running at 4900 rpms flat out and doing about 43 mph.

How do I work the electric choke, must you hold it in for a few seconds and must I pump up the ball?

I am very impressed with this message board and wish to thank those who work hard so a novice like myself can ask questions.

I have read almost every post and learned so much from each.

Where should the trim tab be set, I hope thats what it is, its that adjustable gismo above the prop,

I will continue to visit this site daily and read every post, and again thanks the MarineEngine.com for this service."

"just pump up the bulb first, until it is firm, u will feel it
no hold in the key, which will activate the primer/choke

"Jim, 4900RPM is too low. The correct range should be at least 5200 - 5500RPM. Now your speed is excellent, maybe too good. Use a GPS for true speed, if you haven't. As for your tach's accuracy, only way to validate it's accuracy is to use a known good tach to compare."

"Thanks for the help, I took her out and this time I pumped the ball hard and pushed the key in while starting and it helped, but it was 28 degrees so I guess any motor will start hard when its that cold.

I put a new trim tab above the propeller and she does not pull to the right anymore.

I have play in the stearing and am afraid that I could loose my stearing, I want to buy a new stearing wheel and housing, is this something I can install?. a new stearing cable has been put on by previous owner, the play is not in the cable but in the stearing wheel gear box.
Thanks."
