Yes I even bought a 28ef hp off of them to replace the old one in the 422. They are a Great engines but as you know in Hot weather they tend to vapor lock. Being mounted down in that tub there is just not enough air flow for them. It is a problem but i kind of wish it were more of a problem. That being it has not be a big enough problem for me to take time to solve it. Added an extra fan to one and sometime i just cool them off with a water hose. If it were a bigger problem I would do a redesign on the cover. Never a problem when ambient air is 80 deg or less. Starts very well in cold weather. Oh yes they said they would never use that motor again.
