Results of a survey

40 we currently have under contract
Starboard and port engines were Volvo
model# MD2030B. Recently the port sail drive was replaced with a Model 130SB and gear
ratio 2:4. The starboard sail drive is probably original to the boat and was a Model 120SD with a gear
ratio of 2:9. The sail drives were fitted with 2-blade folding props.
Has anyone else seen 2 sail drives on the same boat with differences in the gear reduction ratio? This may not amount to anything significant but I was curious any possible problems. I could not feel any difference at the helm
but the rpms at the props would be different due to the different ratio's. The props diameter and pitch
were the same.
Any thoughts or concerns?
