gjb Posted September 30, 2014 Report Share Posted September 30, 2014 Well no one seems to want to do any deals was going for the quicksilver 755 but as i say no one wants to do deals so i am going down the other way and fitting a mariner 150 + sport trim tabs to my boat and hoping for the best so saved over half my cash so as i said keep my fingers crossed Graham Quote Link to comment Share on other sites More sharing options...
Maverick Martin Posted September 30, 2014 Report Share Posted September 30, 2014 Foxy Fisher will be the most over powered 640 in our area. Not sure what size engine 640's are rated for but have you checked that insurance will be ok with that size engine? Quote Link to comment Share on other sites More sharing options...
gjb Posted September 30, 2014 Author Report Share Posted September 30, 2014 the weight of the new 150 is almost the same as my old one and smaller and across the channel they rate them for the old 135 and that is heaver so i thought i would go for it graham Quote Link to comment Share on other sites More sharing options...
Mal Thomas Posted September 30, 2014 Report Share Posted September 30, 2014 Hi Graham Have you done the deed and bought it? I have a 640 pilothouse like yours, Im based at ribs marine Christchurch. Have you spoken with Simon there who is the main agent for Quicksilver. By the way like you I have toyed with changing the engine, I have a 115 mariner 4 stroke. I have done a lot of research and the best weight to power ratio is the yamaha by far, on average the yam is 40 kilos lighter which is huge on the handling and fuel consumption and a quieter engine with better security and user dials. By the way your boat is only recommended for 115hp 85kw so you would have to notify your insurance. Quote Link to comment Share on other sites More sharing options...

fisherman1055 Posted September 30, 2014 Report Share Posted September 30, 2014 Hi yes all going ahead and will speak to ins company but just feel i have dead spots with 115 graham Dead spots? Is that when the boat is in the air and the prop out of the water! Quote Link to comment Share on other sites More sharing options...
gjb Posted September 30, 2014 Author Report Share Posted September 30, 2014 No won't be that fast just feel the need for 10 to 12 mph with comfort of course 😉 Quote Link to comment Share on other sites More sharing options...

Rob Posted October 1, 2014 Report Share Posted October 1, 2014 Could a new prop be a cheaper solution? 4 blade maybe? Quote Link to comment Share on other sites More sharing options...
gjb Posted October 1, 2014 Author Report Share Posted October 1, 2014 Thankyou Wedger I don't know if the prop would be the answer or not i just thought something with a bit more grunt and with the trim tabs i hope and pray this will do the trick but will know more in a week or two graham Quote Link to comment Share on other sites More sharing options...
gjb Posted October 1, 2014 Author Report Share Posted October 1, 2014 I think in about three years time if the outboards keep going down in size i should be able to put a 300 hp on Maverick Martin 1 Quote Link to comment Share on other sites More sharing options...

Mal Thomas Posted October 1, 2014 Report Share Posted October 1, 2014 Hi Graham the info I gave you was straight from my identity plate which is mounted on the port side stern. My understanding is that the transom has to be strong enough to cope with the thrust/ push of the engine, along with many other factors. I am sure all this should have been checked by your fitter. Would you be so kind as to invite me down for a quick blast when all sorted I would be very interested in the results. Cheers Mal.

Jim Posted October 1, 2014 Report Share Posted October 1, 2014 Yeah ! Be keen to see it when it's done. If I see you out there I'll show you a clean pair of heels. But only if it's flat calm.
