Its only small, but size doesn't matter. The floor space is slightly larger than a 175 owing to its outboard not taking cabin room and its slightly wider beam. Its a 2-stroke 90HP which is good for 50mph with the 4 blade stainless prop it has on it and the engine is a doddle to work on - although typically 2-stroke noisy. It was purchased new in 2002 from Windermere Aquatic. We went to get the 175 but ended up with this instead. I miss the quietness of the 4 stroke when pottering about on the river, but this costs a total of £20 a year to service!!!
