Longtail thailand

[tabanaza]

Looking for a company/individual in Asia (thailand/indo/viet etc) where I can purchase a longtail with a diesel changfa R180 or yanmar (10hp+-)motor attached or its already compatable with these models of engine. I need it to power a 21 foot fibreglass canoe with about 5-7 passengers. I found one website www.kkkgroup.net located in Bangkok, looked promising, but they are only offering longtails compatable with gasoline engines only, as Ive already contacted them. Ive also been looking at www.goodsdirect.net, however their motor does not mount to the transom, and I want a yanmar/changfa type diesel motor. One more question: Are most longtails compatable with Saltwater? Ive searched these forums so I know someone out there has a handle on these things. Thanks
