We have model RDE-19 C Johnson Seahorse 35hp and we have been trying to get it going. (It was given to us) Anyway everything seems pretty good we even got the pressure tank but it has no fittings and the only ones I see online are around $95.00 for each and we need both ends. So we were wondering if it will be cheaper to convert it to the regulas gas tank type but I guess you have to add a fuel pump? Does anyone have any info or suggestions about this? Ive seen online about converting a smaller hp engine but nothing over 20hp so im wondering if you even can on these? Thanks in advance.
