AVON SR 4.7 & 90 HP suzuki 2009 4 stroke
My 1998 4.7 Searider is currently mounted with a 65hp 1998 suzuki. When waterskiing (+80kg persons or starting on one ski) or carrying 4 divers with twin tanks and stages (+300kg equip, 320 kg persons, 50 liters of fuel, ancher, A-frame, Steering console, ect.) the boat seems a bit underpowered. I had it 11 years so it's definately not a "show-stopper" but more power in those situations would be very nice. I rarely or never do any high speed sailing since i use a relatively small propeller and mainly use the boat for diving, fishing and water-skiing.
for several years i've considered to mount a 90 hp engine allthough i'm aware that is only rated for 70hp. To keep the weight down a Tohatsu 2-stroke 90hp (TLDI) could be an option (146kg). Lately Suzuki came out with a 90 hp 4-stroke only weighing 155kg. This is 38kg lighter than their previous model which i believe is way to heavy.
My current engine weighs 113 kg. I can't find the max weight rating for the SR 4.7 meter anywhere.
The 5.4 meter Searider is classified for 90hp or maximum 175 kg
The transom on the SR4.7 and the SR5.4 are the same. So i guess it's not an issue about the transom cracking up but more a stability issue.
The Seariders has the open hull system for better stabilty at idle but i've closed those holes with inspection hatches to overcome the underpowered engine. I guess with a larger engine i could start using the ballast system as it was intended.
Buying a bigger boat is not an option at this moment. I'm happy with the size of mine and it's in perfect condition.
Under the circumstainces mentioned do you think it would be crazy to go for a 146 or 155 kg 90 hp ?
Has anybody tried to overpower a Searider (4.7) ?
