Re: New motor for RL28
Have you tried the new Honda 10 or 15hp? I thought they did fit but that was quite a tight fit. I think the Honds are the lightest of the 4 strokes too.

Mercury 20 hp 2 stroke fits easily and the 2 stroke is a lot lighter than the equivalent 4 stroke. The 2 stroke uses more fuel but that is not usually a problem on an RL unless you motor a long way. Note that there are two lines of Mercury 2 strokes, one is lighter than the other which is a big advantage on light boats like RLs.

do you know where i can obtain measurements on the various outboards re mecury etc as the manufacturers web sites do not contain this information. may be a 9.9 hp mecury 4 stroke would fit ? the mecury 2 strokes look like it could fit

Don't overlook Tohatsu motors. Most small (under 40) Mercury's and Mariners are re-badged Tohatsus. I'm fairly sure the web site gives specifications

Thanks Mike

purchased 15 Hp Tohatsu 4 stroke based on their advice on dimensions of the motor.

bad news the tohatsu 18 hp 4 stroke same size as the 15 hp tohatsu is to deep and requires transome modification - the skeg is about 140 mm below the hull and could be lifted as there is still clearance under the tiller - will now try a 9.9 Hp prob big foot as 9.9 hp seems from the motor review give less issues - it is a shame that honda redesigned their 15 Hp 4 strokes to be a larger motor with more mass

Hi, I fitted a 2006 model honda 10 HP 4 stroke short leg replacing a Johnson 9.9 and had no problems. However i think this boat has been modified in the past. One thing worth mentioning, the length of the leg is good placing the prop in the correct position but i can't get full tilt as the skeg hits the stern. The honda has a half tilt position and lifts the prop out of the water. I am pleased with the perfromance from this out board so far.
