parts for marine engines are expensive stuff. not to forget labour cost.....here in norway it will cost aprox. 10000euro to save a100hp engine of newer age if just submerged....saltwater arent good fore motors... but i dont know prices in engand,and if thats the price i dont think it woud be worth it...
It cost $1400 to $2000 for a rebuilt powerhead here in the states, plus shipping, plus labor to install. So $3000 is about right.<br /><br />Seems like you might be able to have your current unit rebuilt for a little bit less.
