Does anyone know the difference (apart from HP) between 8HP and 9.9HP Mercury Mariner four stroke models from 2005 & 2006 (2007)?
Both engines look the same and the data in the brochures is identical including the weight.
Have Mercury restricted 8HP in some way or 9.9HP has different carb&jets too? Would appreciate if anyone has any info on this.
Please see the photo of my 8HP below if this helps.
8 & 9.8 models are the same engine, both 209 CC, 8 carb restricted, that I know there isn't any 9.9 model in four strokes only in two strokes, next four strokes models/range are 15 & 20, both 351 CC, 15 being carb restricted. 8 & 9.8 weights the same 37 kilos, All Tohatsu made in Japan.
