How you pay
No card details are taken on this site. Pick how you intend to pay and we email the details with your invoice, then confirm receipt before anything is dispatched. Choosing cryptocurrency takes 2% straight off the order total.
Order to delivery
Send the model, year and serial range. We confirm the part number and tell you what supersedes it if the number has changed.
You get the part price and the freight to your ZIP in one figure, with the payment details for your chosen method.
Small parts by parcel, engines and outboards crated on a pallet. Typically inside 48 hours of cleared funds.
Inspect before you sign and note anything on the paperwork. That note is what makes a freight claim possible.
What customers say
Great experience with Tsonev Spare Parts. The parts were exactly as described, and the quality was excellent. Highly recommended!
Very happy with the service. My order arrived on time, and everything was properly packed. I will definitely order again.
A reliable supplier for spare parts. The ordering process was simple, and the team was professional and helpful.
Before you order
Anything not covered here, call or WhatsApp +1 (209) 373-5717 and speak to someone who reads parts diagrams for a living.
Give us the model, the year and the serial number range and we will confirm it before you order. Every listing shows its part number — if it does not match the number you were given, call us rather than ordering and hoping. A five-minute call is cheaper than a return.
Not necessarily. Manufacturers supersede part numbers regularly, and one current number often replaces two or three older ones. Send us the number you have and we will tell you what supersedes it.
It is quoted per order, because a set of gaskets and a 425 HP outboard are not the same shipment. Tell us your delivery ZIP and whether the address is commercial or residential, and we will quote the part and the freight together before you pay.
No, deliberately. We settle by Zelle, bank wire, Cash App, Chime, Apple Pay and cryptocurrency, which keeps prices down on equipment this heavy. Crypto orders take 2% off the total, and no card details are ever entered on this website.
New equipment carries the original manufacturer warranty, passed through to you in full. Periods vary by brand and by whether the use is recreational or commercial — the documents supplied with your purchase are the authority.
Within 30 days, if it is uninstalled and in its original packaging. Contact us for a return authorisation number first. Anything installed, run or disassembled cannot come back — that is a resaleable-condition limit, not a preference.
Talk to the parts desk
No call centre and no quote-chasing — you get a real figure, in writing, from someone who can read a parts diagram and knows what supersedes what.
