My service manual says to inspect and replace if necessary the exhaust guide/manifold every 1,000 hours. I'm only at 500 hours but planning ahead.
While I do my own impellor changes regularly, along with all other annual maintenance, it seems like doing this check requires removal of the power...
Ordered a new F70 trim tab anode 67F-45371-00-00. Actually, I ordered this: amazon.com/dp/B0DNJKCV87?ref_=pe_125775000_1044873430_t_fed_asin_title
...which claimed to be a replacement for 67F-45371-00-00.
I didn't notice until it arrived that while it was the same size, it was shaped...
Reading my nifty owner's manual for my Yamaha F70, it says to use the oil best suited for the temperatures in my area, and it gives me a nifty chart to look at.
That chart seems to say that 10W40 covers temps from about -15 to about 105F.
Whereas 10W-30 covers about -15 to about 95...
Hi there!
I'm interested in installing a Fell Marine MOB+ wireless kill switch for my F70 with a 703 side control box.
I'm not familiar yet with my 703? How easy is it to access the wiring for the kill switch?
Do I need to remove the whole unit? Then remove the back panels?
Any chance of...
Update:
Replaced all three spark plugs. The old ones didn't look great, not awful, but a bit scorched/dirty.
Replaced the #2 injector coil.
Replaced the #1 fuel injector. The old one did have a bunch of corrosion around the tip (see pic below).
When replacing the #1 fuel injector, when I...
To pop out the #1 fuel injector (on top in the pic) for replacement, I have removed the little metal plate and connector. Service manual says to twist it a bit to break the O-ring seal, then use flat-head screwdrivers to pop it out. I'll try that. Some questions:
1. Any tricks to that?
2...
While under the cowl for a different reason, I noticed some oil on the outside of the oil pump.
I'll check the connections, but is that pump just replaced as an assembly?
Does the pump come apart and is there more I should do to try to find the leak?
Howdy!
Yesterday I took my new-to-me 2010 Tohatsu MD90c2 out on the water for the first time.
After engine ran, even in neutral at idle, for a few minutes, it would have all three lights blink on the tach, and RPM wouldn't go above 3000ish. Stopping/starting the engine didn't seem to make a...
New power boat owner and trying to learn all the mechanical stuff, so I'm likely to ask lots of dumb questions. You've been warned! :)
I've got a 5L Mercruiser A1 sterndrive. Wanted to lubricate the steering actuator valve like my manual and Seloc tell me to. Found the zirc fitting. Hooked...
