Hi all... first post and it's a plea for advice
I have a Yamaha 70 (1995). According to the tachymeter, it's running at approximately 2400-2500 rpm at full throttle. I looked on the Yam website and the current 70s have a range of 5-6k. Unfortunately, this has been the case since I bought it with the boat a couple of months ago (first boat and a boating/outboard newbie). I've been happily using it at this RPM without realising I had a problem (is this likely to damage it??)
The engine has been serviced (first thing I had done after I bought it).
There have been a few instances of where I've pushed the throttle upto max or close to max and it's been running fine until it suddenly loses power. The engine never stalls but I have to throttle back to lowest throttle (not neutral) and all works fine again.
Another thing.... how long should the fuel line be? The line on mine seems quite short... approx 2-2.5 feet. I wondered if this might be a factor? I'm going to change the fuel line/bulb and fuel connections this week I also want to fit a water separator onto the line (is this essential?).
If anyone recognises these symptoms and can offer advice, I'd be most grateful!!
(I'm going to order the clymer Yam manual to get to know this stuff and hopefully do any necessary work myself)
