About Down South Marine
The brainchild of well-known angler, charter captain and legend boat skipper, Rob Naysmith, who, with nearly 60 years of going to sea in boats of all kinds, decided to bring everyone the opportunity to enjoy the benefits of his experience. In his words “a boat is a living thing, it needs to change, it needs care and the love of the skipper, give it that and it will build a lifetime of great memories and always take you home safely”, to this his credo is ‘love your boat’.
Almost 40 years ago Rob and Mercury crossed paths in earnest and he has remained dedicated to the brand since. Since the formation of his charter business in 1993, all his boats have had Mercury outboards fitted exclusively, and that means quite a number of engines. The reasons for this loyalty are Mercury’s ongoing passion in product development, outstanding engine reliability, they’re world leaders in service support and along with delivering unbeatable power, they last forever. So it was inevitable that Rob and Mercury should eventually join forces to bring you the premium quality powerhouse engine backed by a highly experienced support team.
“I’ve seen many boats miss a great day on the water because of engine failure, and our aim is to make sure that doesn’t happen to our clients”.

Big Eye Tuna
Rob & Scott Naysmith I asked my son Scott to give me a hand with this article for two reasons, firstly to give both an old world and new age perspectives on the fishery. Secondly for my own pride in seeing a young angler take the knowledge I gave him, expand on it, and then

Reviews
EXCELLENT Based on 18 reviews Dale Griffiths2025-07-28Trustindex verifies that the original source of the review is Google. After taking my little 5hp outboard in for repairs to a reputable outfit with no luck, I reached out to Rob for assistance. He had just moved his business to Knysna and could not assist me physically (as I am based in a different area). He however offered to assist me remotely free of charge. He then proceeded to meticulously guide me through the process of troubleshooting the motor and we seem to have found the problem. I have learned so much through the process and Rob's passion and knowledge towards outboards and their mechanics is 2nd to none. I would HIGHLY recommend paying him a visit for any outboard related repairs or servicing Be Frank2023-02-19Trustindex verifies that the original source of the review is Google.
