Are these totally rebuilt motors? If not, the price is too high. I'd look for someone that rebuilds. I just bought a totally rebuilt (head sent to machine shop) '98 Johnson 115 for $3895 and it had a 1 year mechanical AND electrical warranty. Looking at my motor, outside and under the cowl, you'd swear it was new. As far as HP, IMO go for a bigger motor, I think you'd like a little more HP than a 70. 8)
