Re: Stus-List Yamaha 4 hp 2 cycle help
Hi David (and Marek), I can't believe it's been so long to reply... I gotta retire soon. I am way too busy now. I like what Marek has determined, below. A couple o' things to add: - not just impeller but often the impediment to cooling flow is a restriction between the block outlet and injection to exhaust. Take apart all the hoses and clean out debris with a wire pick - the crab float shutoff thing is not uncommon in old engines. I have outboard motors and motorcycles dating back to the 70s. On some, to rehab the carb/float situation it is simply a matter of removing the carb gas feed hose and spraying in a cleaner/lube such as WD-40. It cleans any debris and gives a nice film to lube up the needle 7 seat on a carb. If that doesn't work for your situation with dropping gas in the stowed position. I suggest a practical solution that I used in the summer o' '08.. Simply rotate the power head so the tiller handle/ throttle know is facing in the up position. The carb won't drain out in this position. cheers, Russ At 06:42 PM 11/8/2019, you wrote: My $0.02: - Engine sounds as if it is running dry exhaust.

Hi David There is a forum for Yamaha outboards on iBoats forums. I have found it useful in the past with the Tohatsu 6hp we had on our previous boat. The forums are broken up by manufacturer which is nice https://forums.iboats.com/forum/engine-repair-and-maintenance/yamaha-suzuki-outboards Mike Persistence Halifax, NS From: CnC-List On Behalf Of David Risch via CnC-List Sent: November 7, 2019 6:25 PM To: CNC CNC Cc: David Risch Subject: Stus-List Yamaha 4 hp 2 cycle help Anyone have experience working on these?

Re: Stus-List Yamaha 4 hp 2 cycle help
Russ, As do I. I have another outboard that I am now using, but would like to get this little guy running. I have had it a long time. A few things; - Engine sounds as if it is running dry exhaust. Crappy mechanic said it was a "gasket"...where could that be? Its not an exhaust manifold gasket... - When engine tilted, fuel runs out of cowl unless fuel shut-off closed. Said mechanic said a "pin" was missing? Quirky problems that I have not run into before. -Original Message- From: CnC-List On Behalf Of Russ & Melody via CnC-List Sent: Thursday, November 7, 2019 10:11 PM To: cnc-list@cnc-list.com Cc: Russ & Melody Subject: Re: Stus-List Yamaha 4 hp 2 cycle help I love these little Japanese motors but mine (I have a few) usually don't need much work.
