|I had a Southcoast Magnum charterboat with a 10hp Yamaha 4 stroke in the well. I bought the yacht in 1988. Being a charter boat, it did more than 1000 hours a year. |
The yacht was in a pen at Paynesville on the Gippsland Lakes.
Due to corrosion in the leg where the exhaust gasses flow, the dealer recommended replacement every 2 years so we changed it over in preference to waiting for it to fail. I must say, I was disappointe with the life of the Yamaha even though it did work long hours.
I have a RL24 now with a new 5hp Mariner engine in the well. I had problems with all the new outboards being larger than the old models. The only engine that fitted was the Mariner. I will post a report on its performance separately, it works fine.
I posted a fair bit of information on measuring the well and engines as I searched for a suitable engine. If I had an RL28, I would suggest looking at a 8-10hp Johnson 2 stroke with high thrust propeller. Although it is less powerful than some of the other engines, its quality and the modern high thrust propellor will be more than adequate for the RL28. I was less than impressed with all the heavy, clumbsy offerings by yamaha etc. The other brands show no signs of improvement in the last 15 years while the Johnson is a great package with forward shifter and lots of classy finish,
15 years ago the Yamaha was the best with Honda coming second, I see no improvement in their products since then so why do we buy them?
Of course this is my opinion only, I put my money where my mouth is and put a new engine in the well. Don't be afraid of an efficient smaller engine in preference to an old design which does not fit.
