So last week we had run in the tohatsu 50TLDI at loch Lomond and we were just about to start testing, we were moored at Inchmurin island and had a full day of watersports to look forward to, the seapro 500 divemaster RIB was ready to undergo some serious stress testing!! I thought I would ease the engine in gently so my son William was first up on the kneeboard, he was a newbie so I held the board in the water whilst my wife Caz helmed the boat with an experienced observer at her side, the engine pulled the boat out of the water easily and the speed was controlled to perfection, no flat spots at unwanted times like old school carburetted 2 strokes. After Will had his fill I decided to try the double ringo’s these should test the torque of this little lightweight 2 stroke to the max. So with me at the helm, one observer, and 2 adults in the rings (20 stone in the boat and 22 stone behind) I gunned it, the engine labored under full load at 3500 rpm, I thought this was too much for the engine, and I thought I may be about to regret not fitting a new mariner 60hp 4 stroke from our inventory of new outboards for sale, but the little plucky 50hp from tohatsu outboards kept on pulling and after 20 seconds or so the rings had emptied their sluices and up they popped. I was suitably impressed! After this stress test we decided to take some speed readings and I will tell you about this and fuel consumption in the next blog.
