please help!-brought in trophy 2802 "00 twin optimax 225 for replace of trim assembly (engine stuck, hydrolic leak, etc) - and routine maintenece (impeller, filter, plugs, lower gear oil change, lub) ($3.5K)--- Engine was running fine prior, just stuck in up trim position. Incidentally, while inspecting mechanic found corroded lower portion fuel rail with loose connection fuel line, no leaks yet, but recommende repair for safety. Agreed to replace ($1.2K)...they replaced both rails with new direct injects attached. Mechanics took for sea trial to test, and engine block "explodes" with cracked 4" piece aluminum sitting under engine...says piston blew through side....no engine warning lights/overheat/oil lights, just immediately lost power on initial revving beyond idle. Told external computer diagnostics read oil pump /fuel pump ok, and they had done "pre prime" at shop. BTW, I only use the expensive opti oil and tanks and resevoir were full. They are binging back to shop, but claim this failure may have nothing to do with their repair, but will evaluate and let me know.
Is this preignition from faulty feul rail/instillation/plugs? advice would be most appreciated
