Simon, you must readjust your idle throttle limiting screw, and -possibly- the little mixture screw (if the engine cuts out when you open the throttle quickly after having had the engine in idle a few minutes). I have two Suzukis 2.5 and they both work absolutely perfect, in rain or shine, better than any other engine I had before, Hondas, Mercury, Johnsons, two and single cylinder ones.

Simon,
I had the same problem last year with a new suzuki 2.5. It kept cutting out when putting into gear until the engine was fully warmed up. It sometimes cut out even when warm too. It is a common problem. The reason for this is that to pass the EU emissions rules the fuel mixture is restricted until the engine is fully warm. A suzuki marine dealer quickly sorted it out by increasing the dia of hole the fuel goes into the carb. It now works perfectly.

Here are some photos of the Suzuki tilt lever from both sides. The curved metal in the second photo is the bit that needs shortening. I have now followed the suggestion that Claus made and it works a treat, although brute force is needed to unbend and then rebend the metal.

I dont have experience with a 2.5 HP outboard. I decided to buy a 5hp, which I have been very happy with, for the following reasons:1. If I want to get home against a strong tide and head wind with all the crew cold and tired I need an engine that will easily cope with it all. 2. A 5 HP has forward, neutral and reverse gear. I think the reverse gear is almost vital. There have been several situations where I have been manoeuvring in a closed space. Having reversed gear has got me out of trouble. The bay raider is a great boat but with no water ballast and no centreboard down the bows can easily blow off own wind when going slowly.

Which one have you got? I have a Yamaha 5HP 2 stroke which I bought a few months ago secondhand for £500. I was told from various sources that a four stroke small outboard would give more trouble than a two stoke. Apparently four stroke is good for large engines but not so good for small ones. I am sure that a 2.5 HP will deliver a reasonable speed under most circumstances. however, I was put off by the lack of a reverse gear. Colin |

The old chestnut of engine size keeps cropping up. I have a Tohatsu 5 hp four stroke on my BR which I always use when I go out to sea. Having just got back in from probably the hariest sail I have had for some time I was very glad of the extra pushing power that it gave me. I have just joined a new club, beautiful location with a good slip and a fairly straightforward (so I thought!) route out to sea. ( www.saltfleethaven.co.uk). Armed with local charts and as much local knowledge as I could glean, I followed some other guys out, when we rounded the corner and approached the bar I was horrified to find what appeared to be a solid wall of breaking waves in front of me, the others all disappeared into the foaming mass of water. Trusting my faithful Bayraider we manfully ploughed on following the buoys (those that didn\\\\\\\\\\\\\\\'t turn out to be seals popping their heads up to admire my BR!), over the bar with breaking waves that I estimated over a metre high all around us until eventually breaking through to calmer waters. This being my first day out at this club and the object of the exercise was to familiarise myself with the route out to sea, I turned around and did it all again! Whilst I agree with a lot that has been said about the smaller outboards and they certainly have their merits I do not think that they would have coped, or gave me the reassurance in taking on breaking surf on a foul tide and against the wind. I knew my Bayraider could handle these conditions and my Tohatsu had the strength to help her along. The only weak link being me! As usual, when chatting to the inevitable admiring group of sailors around me when loaded back on the trailer. An old hand approached saying \\\\\\\\\\\\\\\'Hey boy, you know you sailed straight over the bar. Don\\\\\\\\\\\\\\\'t know why you didn\\\\\\\\\\\\\\\'t just follow the river out. Silly bugger!\\\\\\\\\\\\\\\' He said, shaking his head and walking off! |

I have completed a 36 nautical mile round trip motor sail with a Suzuki 2.5 mounted on my BR. On the way out because there was virtually no wind and on the way back because the wind, when it occasionally appeared, was on the nose. The whole trip took about 8 hours and I used approximately 4 litres of fuel. The trip out was unballasted and the trip back, to help cut through a short chop (despite the lack of wind) ballasted.
I used my tiller tamer/central steering mod for at least 10 NM, mainly to get away from the noise of the engine. The engine should be relatively quiet under normal circumstances but a substantial amount of noise is generated by my engine top casing vibrating against the engine. I have tried to suppress it using bits of foam etc but will do a more professional job when I get back to the UK.
I also suffer from the flat spot and stalling just after idle and will try to get this fixed with the first service. Exhaust fumes are barely noticeable. Much more noticeable are petrol fumes when the engine is tilted and the fuel cap or air vent are not tightened sufficiently (which is a lot). Otherwise, the engine has been reliable and man enough for the job.
Internal combustion engines are not allowed on Lake Bala, where I do most of my sailing. The 36 NM trip was a complete aberration - it was to meet for lunch and fish on the way but the admittedly quite large planer board and tuna lure I was trolling knocked a whole knot off my speed, so I quickly gave that idea up. Nearly all my normal engine use is for short manoeuvres of much less than 1 NM. So I still hanker after a quiet and smell-free battery powered Torqeedo, if only they would get their short shaft measurements sorted out so that the engine can be tilted up in the BR engine well.
