We are looking to source some new 4 stroke 5hp long shaft outboards. We have used both Suzuki and Honda in the past but I wanted to get some views on the best 4 stroke for the money in this size range.
I use a Merc. It seems to be totally reliable and will plug away all day on tickover (why the previous owner changed from 2 stroke - he parked in a marina with a queue for the lock) and economical (Cherbourg to Xchurch on 12 litres in flat calm and pouring rain) but MUCH noisier than 5hp 2 strokes.
I've got a honda BF5 which came with the boat. It has let me down and I wouldn't have another. Guy on the next pontoon had his on the boat for a week and the ports clogged with salt.
I have a old Yamaha 2 stroke 6 hp twin and a new Suzuki 4 stroke 6hp single.
When I had to replace the Yam the Yamaha salesman told me his engines are the Rolls Royces of outboards. I agreed with him but as I drive a Ford I bought the Suzuki for £300 less.
I agree. I had a Yamaha 4str 4hp and it performed beautifully. It seemed every bit as powerful as the Honda 5hp.
I never had to use it above half throttle on an 18ft yacht. No point as it achieved hull speed at less than half throttle.
It was pretty quiet too.
