Results of a
survey on a 98
Manta 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?
Thanks
