I rebuilt the lower unit including all seals and water pump impeller. Not For Sale!

My father in law seen where they recommend you to re set the gaps in the spark plug and he needs to know the distance for teh gap of a '76 evinrude 70 hp boat motor. Thanks

i have a '76-70hp johnson- same motor uses L77cj4 champion spark gap .040

I have a small motorboat that has an 8 hp motor. How many mph is that? Thanks!

You are not giving enough information to even make a guess!
What would be needed to work into the fourmla would include:
What kind of boat? Shape of the hull?
What does the boat weigh? How many people in the boat and what do they weigh? Is the bottom of the boat Foul or is it Clean waxed and polished? Are you going with or against the wind and current?How strong are they? What are the sea
conditions ?(waves chop fetch)
If you want to assume that all of the above are medium then guess that your speed would be medium 10 to 15 Konts not MPH

I recently purchased a used boat (1992 18' Balyliner Capri with 120 hp Force motor) and have brought it to the lake only twice. The first time I was able to get it to start, but only after several attempts. Now today, it seemed like it wanted to start, but wouldn't quite turn over. The one time it did start, it cut out as soon as it was put into gear. The attempts after that made little or no noise and I gave up. Also, can someone explain how to use the choke and explain what exactly it does (I'm assuming just pushing the key in while turning to start as it is labeled)? My knowledge of this is very limited so any thoughts on where to start would be appreciated. I was told to try charging the battery, replacing the spark plugs, and using new fuel but would appreciate any other thoughts or ideas.

Take the cover off the engine .replace the plugs ,Charge
your battery ,get a battery tester make sure battery
dc voltage is 1270 or more on dc scale 1270 is the
voltage battery has will only show that if fully charged
drain and put new gas in tank..make sure you have the
correct oil mixed with gasoline if a mixture is called for
very important make sure you disconnect gas line from
engine disconnect quick change coupling from gas line
and make sure when you squeeze the gas bulb until gas
comes out the line is possible gas line fuel filter clogged
ok. you now have gas.replace coupling and reinsert in engine.
pump up gas bulb until very very hard . shoot a little
starting fluid in engine air intake now start engine . make sure you have water for the engine if it is out of the water.
Choke go by the sound of the engine adjust to where
engine turns the fastest and tries to start.I personally
think the purpose of a choke is to keep engine running
until it gets to operating temp Good Luck.
