    1958 seahorse 10 running hot

    pulling the head isn't so bad try not to break the base gasket and any carbon seals... if any on the drive shaft see a CD version good time to can clean out the exhaust carbon in the lower unit :)

    1958 seahorse 10 running hot

    ok you changed the impeller. Was the engine run before the change ? and what is hot and then you went ahead with the change or did it just become hot after your work ? did you do any gasket work ?

    Surging Johnson 6 hp.

    Bummer I guess .... suggestion... up to you .....but if your 4hp works fine transfer the magneto parts to the 6hp. if surging stops you found the area of concern. if surging does not stop...fuel starvation is occuring..... back to fuel , carb, hose tank issues. Try the engine with...

    well if not fuel quality, not a plugged up carb, good hose good filters , good fuel pump etc....ignition could be a cause. condensers even new ones can be bad or react to heat build-up. VOM testing of condensers is not conclusive unless truly bad. points being mecanical less...

    make certain the bottom fat donut #21 is installed to !! do not use a big wire ... use carb cleaning tools or small mono line in jet orifices. make certain float is not upside down ... it should drop level with the carb bowl.

    have you tried hand pumping fuel when it does start to falter ? Tank vent open ? and working ? hose is good ? needle clip on the float is installed ? cooling OK ???

    2004 Evinrude 115

    agree but... would you buy a 20 year old engine with " harder" to find injectors and unknown history. Don't get me wrong my 2005 has run great for 18 years but 2024 is coming up and as years go by... the future is uncertain. My 2 stroke kickers (small Mercs or OMC) from the 60's...
