I grew up with a 1976 Spectra 22 .... I still have the boat. It has little under 200 hrs. The boat is completely original and looks like just left the showroom. Completely stock ... I will tell you that spent many years around jets of this era. Even though Berkeley says ok .... it still not a good idea. The impeller and seals need the lubrication... why take the chance.
@@williamderosa8947 and our Sunkisst has been in our family for 40+ years and it hasn't hurt it. As a mechanic myself, I'm usually going to go with what the manufacturer said, you, since THEY made it
Obviously from 2 schools of thought. This from a forum on running jet pumps dry “The Berkeley techs I talked to back when I had a jet (early 1980's) both said to have it in the water whenever running it. As I recall it had to do with the balance of the impeller more than anything (which would imply undue wear ring or impeller wear. The main bearing is sealed and not water cooled. The bushing on the other end is in an oil bath. The packing would only need a little water to keep from burning up” . My thinking is an ounce of prevention better then a expensive rebuild. BTW … beautiful boat … enjoy !!
@@williamderosa8947 I definitely agree with you on the balancing aspect for sure, that keeps it on an axially straight path, assuming obviously the pump shaft is straight and it's held on a straight line, but water is not a lubricant in any way, it just cools parts going through it. And I'm saying it never bothers me because that's how I've had to tune the carburetor on ours since we have such a high lift and duration cam in it now, And we've rebuilt our pump a couple years ago so I know everything on the inside is okay
