1979 Johnson 70hp 3cyl. Excellent cond. hood is removed! maintenance and upgrade tips please!!!!!?

I'm 15 and I LoVe my Boston Whaler. It's a 1975 15ft. Whaler Sport. My father let me use his alumnacraft last year. He gave it to my uncle for his house up north, leaving me without a boat. All my neighbors and practically everyone in our yacht club have whalers. Ironically, our neighbors were selling theirs so my dad bought it for me! I love engines n high performance. Alot of people on our lake have smaller whalers, mostly 13 footers with 25-50 hp motors on them. not mine! I got 70! The kid's like to race eachother and stuff. People always made fun of my crappy tin boat. But im more respected with my whaler. I recently installed a whale tail stabilizer fin. Now its really fast. tops out at 48mph. So far I have the fastest whaler. I've never lost a race with it yet.



In a few weeks, I'm going to take it out and restore it.

That's cool. Understand that every boat has what's called a maximum hull speed. When that speed is exceeded, the boat will chine walk, and if not slowed down it will roll over. The fact that you get 48 mph out of it is awesome! Install a tach and make sure you are topping out between 5400 and 5600 RPM. Make sure you keep up on your gear oil, water pump, spark plugs, and fuel filters. Have fun.1979 Johnson 70hp 3cyl. Excellent cond. hood is removed! maintenance and upgrade tips please!!!!!?
if you're going to race it, you need Boysen reeds. go .002" over on the main jets and replace the fuel pump. then you can prop down an inch and rev to 5800. could be a real sleeper.1979 Johnson 70hp 3cyl. Excellent cond. hood is removed! maintenance and upgrade tips please!!!!!?
I have a 70hp Johnson on my bass boat. I bought it 3 years ago not knowing a whole lot about boats or motors. I found this site on the internet and joined the forum. I have learned a great deal there. I only go back in when I need some bit of infromation. They also have an online parts warehouse which I have used a bunch. They also email me sales, and specials.

I hope to see you in the forum, good luck!
